The authors discuss the limitations of photography in producing representations that lead to the accurate perception of shapes. In particular, they consider two situations in which the photographic representation, although an accurate reproduction of the geometry of the two-dimensional image in the eye, does not capture the way human vision changes this geometry to produce a three-dimensionally accurate perception. When looking at a photograph, the viewer's uncertainty of the camera-to-subject distance and the fact that, unnaturally, a photograph presents almost exactly the same view of an object to the two eyes result in substantially distorted perceptions. These most commonly result in a perceived flattening and fattening of the 3D shape of the object being photographed.

In the displacement measurement inside a specimen by speckle photography, it is not easy to get clear Young's fringes images. Stress-intensity factors of mixed mode can be estimated by embedded speckle photography. However, the error of the stress intensity factor inside a specimen was considerably large. To evaluate the 3-D stress field inside the specimen from displacement data on the free surface obtained from the 2-D intelligent hybrid method, we developed the 3-D local hybrid method based on an inverse problem analysis. The accuracy of the 3-D local hybrid method varies depending on the depth of the plane of error assessment, hybrid domain size, and specimen thickness. Hence the optimal analysis conditions were discussed.

In early twentieth-century France, syphilis and its controversial status as a hereditary disease reigned as a chief concern for physicians and public health officials. As syphilis primarily presented visually on the surface of the skin, its study fell within the realms of both dermatologists and venereologists, who relied heavily on visual evidence in their detection, diagnosis, and treatment of the disease. Thus, in educational textbooks, atlases, and medical models, accurately reproducing the visible signposts of syphilis – the colour, texture, and patterns of primary chancres or secondary rashes – was of preeminent importance. Photography, with its potential claims to mechanical objectivity, would seem to provide the logical tool for such representations.Yet photography’s relationship to syphilographie warrants further unpacking. Despite the rise of a desire for mechanical objectivity charted in the late nineteenth century, artist-produced, three-dimensional, wax-cast moulages coexisted with photographs as significant educational tools for dermatologists; at times, these models were further mediated through photographic reproduction in texts. Additionally, the rise of phototherapy complicated this relationship by fostering the clinical equation of the light-sensitive photographic plate with the patient’s skin, which became the photographic record of disease and successful treatment. This paper explores these complexities to delineate a more nuanced understanding of objectivity vis-à-vis photography and syphilis. Rather than a desire to produce an unbiased image, fin-de-siècle dermatologists marshalled the photographic to exploit the verbal and visual rhetoric of objectivity, authority, and persuasion inextricably linked to culturally constructed understandings of the photograph. This rhetoric was often couched in the Peircean concept of indexicality, which physicians formulated through the language of witness, testimony, and direct connection.

High-resolution 3-dimensional photography offers unparalleled advantages in objective and detailed skin contour characterization, quantification, volumetric and surface area analysis. This study aims to illustrate the benefits of 3-dimensional photography through analysis of noninvasive reduction of submental fat using cryolipolysis. A nonrandomized prospective analysis was performed of 14 selected patients who underwent treatment with cryolipolysis (CoolSculpting System; Zeltiq) between February and June 2016. The benefits of 3-dimensional photography (Vectra; Canfield Scientific) are presented. High-quality 3-dimensional images are presented to illustrate the utility of 3-dimensional photography as a means to quantitatively evaluate changes in submental volume, fat thickness, and surface area reduction, thereby exemplifying the broad applicability of this imaging technique. Three-dimensional photography technology provides clinicians with enhanced options that extend beyond simple 2-dimensional photography. Our study illustrates the benefits of the technology for accurately measuring volumetric changes after submental cryolipolysis treatment.

Three-dimensional Rayleigh-Taylor instability, induced by accelerating a small volume of water down a vertical tube using air pressure, is investigated. Two geometries are studied: a 15.875 cm circular tube and a 12.7 cm square tube. Runs were made with initial disturbances in the form of standing waves forced by shaking the test section in a lateral direction. Accelerations ranging from 5 to 10 times gravitational acceleration and wavenumbers from 1 cm−1 to 8 cm−1 are studied. The resulting instability was recorded and later analysed using high-speed motion picture photography. Measurements of the growth rate are found to agree well with linear theory. In addition, good qualitative agreement between photographs and three-dimensional surface plots of the weakly nonlinear solution of Part 1 of this series (Jacobs & Catton 1988) is obtained.

Psychiatric genomics research protocols are increasingly incorporating tools of deep phenotyping to observe and examine phenotypic abnormalities among individuals with neurodevelopmental disorders. In particular, photography and the use of two-dimensional and three-dimensional facial analysis is thought to shed further light on the phenotypic expression of the genes underlying neurodevelopmental disorders, as well as provide potential diagnostic tools for clinicians. In this paper, I argue that the research use of photography to aid facial phenotyping raises deeply fraught issues from an ethical point of view. First, the process of objectification through photographic imagery and facial analysis could potentially worsen the stigmatisation of persons with neurodevelopmental disorders. Second, the use of photography for facial phenotyping has worrying parallels with the historical misuse of photography to advance positive and negative eugenics around race, ethnicity and intellectual disability. The paper recommends ethical caution in the use of photography and facial phenotyping in psychiatric genomics studies exploring neurodevelopmental disorders, outlining certain necessary safeguards, such as a critical awareness of the history of anthropometric photography use among scientists, as well as the exploration of photographic methodologies that could potentially empower individuals with disabilities.

Graphic illustration by a scientifically trained artist provides a panoramic view of the sea floor unobtainable directly by photography. Detailed photographs, direct observations, and field sketches are combined to produce a photographically documented hypsographic reconstruction of the sea floor. Dry submersible or diver traverses show only a sequence of closeup photographs because of the visibility limitations presented by the ocean environment. At present the large scale aspects of the topography are best developed from direct observations. The underwater photographs arranged in traverse sequence serve to refresh the memory and provide topographic, geologic, and biologic detail. The resulting detailed illustration gives a three dimensional composite panorama of the sea floor. This combined artist-photographic technique has been applied to: submarine cable routing, habitat emplacement, and geological and biological reconnaissance.

Abstract BACKGROUND: Accurate localization and visualization of subdural electrodes implanted for intracranial electroencephalography in cases of medically refractory epilepsy remains a challenging clinical problem. OBJECTIVE: We introduce a technique for creating accurate 3-dimensional (3D) brain models with electrode overlays, ideal for resective surgical planning. METHODS: Our procedure uses postimplantation magnetic resonance imaging (MRI) and computed tomographic (CT) imaging to create 3D models of compression-affected brain combined with intensity-thresholded CT-derived electrode models using freely available software. Footprints, or “shadows,” beneath electrodes are also described for better visualization of sulcus-straddling electrodes. Electrode models were compared with intraoperative photography for validation. RESULTS: Realistic representations of intracranial electrode positions on patient-specific postimplantation MRI brain renderings were reliably created and proved accurate when compared with photographs. Electrodes placed interhemispherically were also visible with our rendering technique. Electrode shadows were useful in locating electrodes that straddle sulci. CONCLUSION: We present an accurate method for visualizing subdural electrodes on brain compression effected 3D models that serves as an ideal platform for surgical planning.

This article presents an overview of the history, principles, and current developments in the media technological field of photogrammetry. By chronicling the isomorphic shift taking place in image capturing, we seek to show that photogrammetry has led the way forward in seeing technical images not only as two dimensional projections, but as three-dimensional model-based images. In the mid-nineteenth century, photogrammetry was first used for the documentation of architectural objects and it later became a standard technique in aerial photography. Although its fields of application have become more extensive, photogrammetry’s basic principle hasn’t fundamentally changed: it is still defined as the three- dimensional geometric reconstruction of two-dimensional photographs through the measuring of reference points. With digital technological standards and advances in camera technology, photogrammetric imaging nowadays is intensively used for object recognition in machine vision and robotics. Beside this, photogrammetry is also opening new possibilities for documentation in the fields of investigative arts, this being explored with a discussion on the “Ground Truth” project from Forensic Architecture. Keywords: investigative art, machine vision, object recognition, photogrammetry, photography

In the concept of the process signature, the relationship between a material load and the modification remaining in the workpiece is used to better understand and optimize manufacturing processes. The basic prerequisite for this is to be able to measure the loads occurring during the machining process in the form of mechanical deformations. Speckle photography is suitable for this in-process measurement task and is already used in a variety of ways for in-plane deformation measurements. The shortcoming of this fast and robust measurement technique based on image correlation techniques is that out-of-plane deformations in the direction of the measurement system cannot be detected and increases the measurement error of in-plane deformations. In this paper, we investigate a method that infers local out-of-plane motions of the workpiece surface from the decorrelation of speckle patterns and is thus able to reconstruct three-dimensional deformation fields. The implementation of the evaluation method enables a fast reconstruction of 3D deformation fields, so that the in-process capability remains given. First measurements in a deep rolling process show that dynamic deformations underneath the die can be captured and demonstrate the suitability of the speckle method for manufacturing process analysis.

Operating and managing single three-dimensional building model individually are critical in the application of oblique photography models. However, these models are usually complete and continuous, and the single three-dimensional building model in these models cannot be managed individually. Generally, achieving a single three-dimensional building model requires a human-computer interaction to determine the cutting range, but this process is time-consuming and inefficient. To overcome this problem, this study proposed a new method for automatically achieving single three-dimensional building model without the need for human-computer interaction. First, the point clouds of an oblique photography model are divided into virtual grids, and the point clouds in each virtual grid are seen as a whole. In this way, the number of point clouds involved in the calculation is reduced, thereby improving computing efficiency. Second, the point clouds of a building facade are extracted by setting the height difference. By comparing the height difference between the highest point and the lowest point of the grid with height difference threshold, all point clouds in the grid that do not meet the requirements are eliminated. Third, the point clouds of the building facade are classified, and the contour line is extracted by the classified point clouds. Finally, the single three-dimensional building model is achieved by reconstructing the triangles that intersect with the extracted contour line. Experimental results show that the proposed method can effectively achieve single bodies automatically from an oblique photography building model. This method is then useful for achieving single three-dimensional building model from massive oblique photography data.

Multi-model photogrammetry enables precise three-dimensional measurements from strips or blocks of overlapping small-frame photographs (colour slides). The method can be used for geo-scientific terrain analysis and mapping. Of special interest is the ability to map otherwise inaccessible terrain features such as geological outcrops on steep mountain faces and canyon walls. Field photography is carried out without special photogrammetric training using ordinary small-frame cameras. Photographs can be taken at any scale and angle from terrestrial stations, helicopters, light planes, or boats. In the laboratory, strips or blocks of small-frame photographs are set up in an analytical stereo-plotter where multiple stereoscopic model pairs are simultaneously orientated. Interpretation and compilation is continuous across model boundaries. Data can be plotted in many different projections. The multi-model photogrammetric technique is explained and procedures are outlined for camera calibration, photography, and acquisition of ground-control information.

Abstract BACKGROUND: There have been no studies of the structure and safe surgical entry zones of the brainstem based on fiber dissection studies combined with 3-dimensional (3-D) photography. OBJECTIVE: To examine the 3-D internal architecture and relationships of the proposed safe entry zones into the midbrain, pons, and medulla. METHODS: Fifteen formalin and alcohol-fixed human brainstems were dissected by using fiber dissection techniques, ×6 to ×40 magnification, and 3-D photography to define the anatomy and the safe entry zones. The entry zones evaluated were the perioculomotor, lateral mesencephalic sulcus, and supra- and infracollicular areas in the midbrain; the peritrigeminal zone, supra- and infrafacial approaches, acoustic area, and median sulcus above the facial colliculus in the pons; and the anterolateral, postolivary, and dorsal medullary sulci in the medulla. RESULTS: The safest approach for lesions located below the surface is usually the shortest and most direct route. Previous studies have often focused on surface structures. In this study, the deeper structures that may be at risk in each of the proposed safe entry zones plus the borders of each entry zone were defined. This study includes an examination of the relationships of the cerebellar peduncles, long tracts, intra-axial segments of the cranial nerves, and important nuclei of the brainstem to the proposed safe entry zones. CONCLUSION: Fiber dissection technique in combination with the 3-D photography is a useful addition to the goal of making entry into the brainstem more accurate and safe.

Photographic resources are well known within museum contexts. However, these images are rarely considered in terms of how they enhance the historical value of museum objects, construct aesthetic and ethnographic meanings, and interpret museum collection practices. This paper examines the multi-media collections of Eliot Elisofon, an internationally known photographer and filmmaker who traveled in Africa from 1943-1972. The Elisofon collection at the National Museum of African Art contains both photographic materials and three-dimensional objects created and collected in the course of Elisofon's professional career. I explore the ways in which Elisofon's images have been used to illustrate objects in situ, represent cultural contexts of use and meaning, and create multiple layers of authentication for the objects (i.e., artistic, documentary, ethnographic). Attention is also given to the importance of photography as a collection practice in and of itself.

Abstract Medical imaging is predominantly a visual field. In this context, prenatal ultrasound images assume intense social, ethical, and psychological significance by virtue of the subject they represent: the fetus. This feature, along with the sophistication introduced by three-dimensional (3D) ultrasound imaging that allows improved visualization of the fetus, has contributed to the common impression that prenatal ultrasound scans are like photographs of the fetus. In this article we discuss the consistency of such a comparison. First, we investigate the epistemic role of both analogic and digital photographic images as visual information-providing representations holding a high degree of objectivity. Second, we examine the structure and process of production of ultrasound scans and argue that a comparison between two-dimensional (2D) ultrasound and photography is justified. This is in contrast to 3D ultrasound images that, due to the intensive mathematical processing involved in their production, present some structural issues that obfuscate their ontological and epistemic status.

Fashion photographs are generally two-dimensional images showing one side of a three-dimensional model. This paper, however, deals with far less well-known stereoscopic fashion photographs. Stereoscopy is a technique that creates the illusion of a 3-D image. Based on the image collection of Swiss textile and clothes company HANRO, the article analyzes the composition of 3-D pictures by putting them in a broader media-historical context. The archived stereoscopic photographs date back to the 1950s and show a series of women’s fashion. In the same period, Hollywood experienced a 3-D-boom that may have had a technical and aesthetical impact on these photographs. Although fashion is not mediated in moving images in this case study, codes or formal languages of a film are inscribed in the images, as will be shown in the following text. Building on these findings, this paper further discusses the influence of cinematography and other media practices on the fashion industry’s attempt to free its fashion imagery from the confines of a two-dimensional page.

ABSTRACT Objective: To clarify, by three-dimensional (3D) facial scans, if 4- to 6-year-old children with intraoral sagittal discrepancies and open-bite occlusion show differences in facial morphology when compared to children without anomalies. Materials and Methods: Scans of 290 children presenting with occlusal abnormalities were compared to 1772 face scans of age-matched individuals photographed with a faceSCAN II® 3D data acquisition system. From these, three study groups were formed comprising 188 children with distal occlusion/increased overjet (Class II), 37 with mesial occlusion/inverse overjet (Class III), and 65 with open-bite occlusion. These groups were evaluated by age and gender for each group compared to the control individuals. Results: The Class II group showed statistically significant reduced dimensions of head width, upper face width, and midface length. In addition, the mean values for mouth width and lip thickness were higher, and their upper lips were located more anteriorly than in the control group. The Class III group exhibited more markedly retruded upper lips. The facial profile of female 5-year-old Class III patients was significantly more concave. Patients in the open-bite group showed reduced upper lip length, with differences only being statistically significant in male 4-year-olds. Conclusion: Dental Class II with increased overjet and dental Class III with decreased overjet influence soft tissue morphology and are represented on 3D facial scans.
