Abstract:

Eye tracking research is a growing area and the fields as where eye trackingcould be used in research are large. To understand the eye tracking data dif-ferent filters are used to classify the measured eye movements. To get accu-rate classification this thesis has investigated the possibility to measure bothhead movements and eye movements in order to improve the estimated gazepoint.The thesis investigates the difference in using head movement compensationwith a velocity based filter, I-VT filter, to using the same filter without headmovement compensation.

<p>In this thesis we present a system to extract the eye motion from a video stream containing a human face and applying this eye motion into a virtual character. By the notation eye motion estimation, we mean the information which describes the location of the eyes in each frame of the video stream. Applying this eye motion estimation into a virtual character, we achieve that the virtual face moves the eyes in the same way than the human face, synthesizing eye motion into a virtual character.

Abstract:

Mobile eye tracking studies in urban environments can provide important insights into several processes of human behavior, ranging from wayfinding to human-environment interaction. The analysis of this kind of eye tracking data are based on a semi-manual or even sometimes completely manual process, consuming immense post-processing time. In this thesis, we propose an approach based on computer vision methods that allows fully automatic analysis of eye tracking data, captured in an urban environment. We present our approach, as well as the results of three experiments that were conducted in ord

Abstract:

Accidents caused by drivers’ drowsiness behind the steering wheel have a high fatality rate because of the discernible decline in the driver’s abilities of perception, recognition, and vehicle control abilities while sleepy. Preventing such accidents caused by drowsiness is highly desirable but requires techniques for continuously detecting, estimating, and predicting the level of alertness of drivers and delivering effective feedback to maintain maximum performance. The main objective of this research study is to develop a reliable metric and system for the detection of driver impairment due

Abstract:

We can detect faces more rapidly and efficiently compared to non-face object categories (Bell et al., 2008; Crouzet, 2011), even when only partial information is visible (Tang et al., 2014). Face inversion impairs our ability to recognise faces. The key to understand this effect is to determine what special face features are processed and how coding of these features is affected by face inversion. Previous studies from our lab showed coding of the contralateral eye in an upright face detection task, which was maximal around the N170 recorded at posterior-lateral electrodes (Ince et al., 2016b;

Abstract:

In normal everyday viewing, we perform large eye movements (saccades) and miniature or fixational eye movements. Most of our visual perception occurs while we are fixating. However, our eyes are perpetually in motion. Properties of these fixational eye movements, which are partly controlled by the brainstem, change depending on the task and the visual conditions. Currently, fixational eye movements are poorly understood because they serve the two contradictory functions of gaze stabilization and counteraction of retinal fatigue.

With the rapid rise of neural networks, many tasks that used to be difficult to complete in traditional methods can now be solved well, especially in the computer vision field.

Therefore, although some embedded systems are powerful nowadays, most embedded systems still suffer from memory and computation limitations, which means it is hard to deploy our large neural networks on these embedded devices.

Abstract:

Yes<br>When we track an object moving in depth, our eyes rotate in opposite directions. This type of “disjunctive” eye movement is called horizontal vergence. The sensory control signals for vergence arise from multiple visual cues, two of which, changing binocular disparity (CD) and inter-ocular velocity differences (IOVD), are specifically binocular. While it is well known that the CD cue triggers horizontal vergence eye movements, the role of the IOVD cue has only recently been explored. To better understand the relative contribution of CD and IOVD cues in driving horizontal vergence, we re

Four steps, extracting a human face, detecting eye location, tracking the eyes and detecting blinking are developed for our system. Using a video camera mounted in the image of the driver’s face is f

Abstract:

碩士<br>國立交通大學<br>資訊科學系所<br>93<br>The information about eye blinks shows one’s fatigue. Detecting blink is useful to monitoring system or warning system. Automatically detecting fatigue of drivers may save them from accidents. We propose a fast algorithm for eye location and eye blink detection. This algorithm is adapted to the complex background and the situation which people wear glasses. In the first place, we classify pixels as skin color and non-skin color to build a skin mask of original image. Second, we patch the skin mask with morphological operations and locate the face bounding block.

碩士<br>國立交通大學<br>資訊科學與工程研究所<br>106<br>This paper proposes a new algorithm for human detection using single downward-viewing fish-eye camera. In recent years, methods for human detection using projective camera have been studied extensively, but researches on human detection from fish-eye camera images are very limited and time-consuming, and most of them were used in simple and uncluttered environments. In addition, the advantage of fisheye lenses is that they can cover a very wide range with only one camera. When people are close, or they may be blocked, using fish-eye camera has a better view

Abstract:

Face and subsequently eye detection is primary step for facial image processing. Most of these applications faces are considered without spectacles that poses challenge to detect ocular features. In this work, we aim to create a facial data-base with and without spectacles to facilitate the validation of algorithms for face or eye detection. We designed an experiment to incorporate variability in several parameters to be detected and measured. We have generated the ground truth to provide a platform for the researchers to quantitatively evaluate the performance of their algorithms on this dat

In recent years, digital cameras and camera phones are more popular. People can take many pictures easily. Some photos taken in dark with flashlight will have some red-eye artifact. This subject becomes more important nowadays. In this thesis, we propose a fast face detection and automatic red-eye reduction method, which eliminates red-eye effect automatically.

To avoid interrupting the driver, it is necessary to build a system under non-invasive and non-contact condition. Image process system suits to achieve such a request. Hence, it is recommended to judge the drowsiness state by observing eye status of operators via eye video. In this thesis, we use a CCD camera as the image sources and use skin color map to segment skin region. Then we use PCA algorith

However, eye detection often misdiagnoses for the interference caused by glasses when one wears spectacles. This thesis addresses an algorithm to automatically detect the eye location from a given face image and separate reflections within glasses while one has worn glasses. Our system consists of three modules: face segmentation, optic-area detection, and the separating of glasses reflections while one has worn g

碩士<br>聖約翰科技大學<br>電子工程系碩士班<br>96<br>Eyes are one of the most important facial features and eyes detection play a quite important role in many useful applications, such as face detection, face recognition, facial expression analysis, or eye-gaze tracking systems. In this paper, the authors introduced an eye localization system based on the line color sequence (LCS) in the color images. The algorithm not only focuses on the identification of color types, but also engages in determining the spatial relationships between the colors. The novelty of this work is that the algorithm works without compl
