Testo completoOur thesis' subject considers specifically the recognition of cartographic objects with a highly composite structure, such as roundabouts and bridges, on high resolution satellite images. Being man-made constructions, cartographic objects have regular geometrical features that distinguish them from other objects. We propose to exploit principally these features in order to obtain a representation of their inherent structure. A method to generate an explicit structural object model represented by Attributed Relational Graphs (ARGs) from images segmented by an expert is first developed. At the end of this preliminary stage we succeeded to generate object models for the roundabout and bridge categories. We then proposed to learn a more flexible model based on the appearances of the local parts of the objects using a statistical learning method. An implicit object model is learned by the fusion of weak classifiers obtained from geometrical primitives using the Adaboost algorithm. An object recognition method using an implicit model constructed by a parts and structures approach is then proposed. The model is learned using the Mean-Shift clustering algorithm. Finally, the methods are validated on satellite images provided by the CNES in the frame of a national competition and a cartographic application

Testo completoSatellite or aerial images are corrupted by the optical system and the sensor. To reconstruct a good quality image from a noisy and blurred observation, one needs to perform a déconvolution. First, we recall the principles of the acquisition chain, from optics to the sensor (visible or infrared), enabling us to model the degradation of the image. In order to reconstruct the image without amplifying the noise, while preserving edges and textures, it is s=necessary to impose constraints on the reconstructed solution, which consists of choosing a prior model. We study satellite and aerial image modeling, which can be done within both probabilistic and variational frameworks, and using both discrete and continuous models. We propose new statistical model that take into account the fractal properties of natural scenes and their non-stationarity, using multiscale and adaptive approaches. Next we study different techniques for estimating the model parameters, describing the properties of the images to be reconstructed. These techniques are developed within a Bayesian framework, and can be solved using either stochastic, or deterministic algorithms, depending on the problem. Finally, we propose new fully automatic reconstruction algorithms. First, we suppose that the degradations (blurring kernel and noise statistics) are known, and we try to reconstruct the unknown image. Second, we consider the case where these degradations are unknown. We perform a blind déconvolution, in two steps, the first step consisting of determining the instrumental parameters, and the second of deconvolving the image with fixed degradation parameters. Tests have been performed on remote sensing data such as satellite images (SPOT 5 and Pléïades simulations) and high resolution visible and infrared aerial images

Testo completoNowadays, new data which contain interesting information can be produced : the Satellite Image Time Series which are observations of Earth’s surface evolution. These series constitute huge data volume and contain complex types of information. For example, numerous spatio-temporal events, such as harvest or urban area expansion, can be observed in these series and serve for remote surveillance. In this framework, this thesis deals with the information extraction from Satellite Image Time Series automatically in order to help spatio-temporal events comprehension and the compression in order to reduce storing space. Thus, this work aims to provide methodologies which extract information and compress jointly these series. This joint processing provides a compact representation which contains an index of the informational content. First, the concept of joint extraction and compression is described where the information extraction is grasped as a lossy compression of the information. Secondly, two methodologies are developed based on the previous concept. The first one provides an informational content index based on the Information Bottleneck principle. The second one provides a code or a compact representation which integrates an informational content index. Finally, both methodologies are validated and compared with synthetic data, then are put into practice successfully with Satellite Image Time Series

Testo completoThe objective of this thesis is to improve the detection of point objects in optical imaging. They focus on the challenging detection of low velocity point objects on inhomogeneous background including areas of strong gradients of gray levels. In this context, we propose single-frame detection methods trying to take advantage at best of the spatial background correlation. Spatio-temporal extensions of the proposed methods are studied in a second time. Based on a formalism of the generalized likelihood ratio test (GLRT), the problem of detection boils down to a two-step process which consists in separating the first and second order estimation of the local background (i. E. Mean and covariance). To improve the performances of the detection methods by first order background modelling, we adapt patch-based denoising method to detection. Despite the improvement of detection performance brought by these patch-based methods, it appears that textures associated with background structures are still visible after the background suppression step. We seek to improve the detection performance by second order modeling. We are interested in matched filter adapted by area based on a Gaussian mixture model. A detailed performance analysis of the developed filters is made from real cloudy background on which point targets are embedded

Testo completoThe analysis of satellites imagery acquired at different dates allows the measurement of Earth surface displacement (earthquake ground deformation, glacier advance and retreat, sand dunes migration, slow-moving landslide,. . . ) that occured between the images acquisitions. In this thesis we investigate 1) the extension of the processing techniques established for satellite imagery to aerial imagery, and 2) the applicability of Earth-based technique to monitor eolian surface processes on Mars. Aerial imagery, whose first acquisition dates back decades before the satellite era, and whose ground resolution is higher than satellite one, can be relevant to monitor Earth surface displacement. We present a methodological extension of the satellite technique to aerial imagery. Potential and limitations are investigated. Application to the Krafla rift opening in Iceland (1975-1984), using aerial imagery, declassied spy imagery, and modern satellite imagery is presented. Next, we applied the method to Mars imagery taking advantage of the high resolution HiRISE instrument. A pair of HiRISE images is processed to monitor the activitys of a dune field. We measured sand ripple migration and inferred a sand flux comparable to some the Earth dune fields sand flux. We then expand our processing to a time-series of 10 HiRISE images, and characterized the seasonal variability of the sand flux throughout the year. This seasonal sand flux variability is used jointly with a sand flux prediction from atmospheric simulations to constrain the sand mobility threshold
