Full textSatellite images of the Earth recently enable geographers to considerably extend the field of their observations. But the numerisation, the processing and the visualisation of these images require a solid and appropriate computer system. In collaboration withe agroup of researchers, the programmer have helped in solving the essential problems posed by the nature of the data to be processed. These data comprise about ten million elementary units called pixels. It was initially nacessary to explore deeply the capacities of e system (the micro-comuter system), for this processing. The latter being developped alongside an IBM PC-AT revealed to be very effective owing to its speccialised cards, its flexible operating system, the md-dos and to the combined usage of two programming languages (the C and the assembler). The initial satellite data were available in a magnetic tape whose reading required a programme extablishing the link between the tape controller and the ibm, important problemq were encountered : inadaptation of one of the IBM Bios function, insufficient tape reading speed using the language C and the delicate link between the latter and the assembler. Once read, the data obtained from the tape were printed the Canon PJ-A080 a for the colour images ; the Epson LQ-1500 and the laser writer MO 156Z for the black and white images while other programmes enabled their visualisation. The laser writer, particularly ets in-built micro-processor gave very satisfactory results. To enable the printing of the results, the image was made to undergo different processing in order to improve ets appearance and to refine ets contracts : by the analyses of frequency histogram, classification, stretching and line-removing. It's possible to make e good interpretation of an erea with Earth satellite image, an appropriate micro-computer system and somme printed images

Full textImaging systems are continuously improving and their uses are spreading more and more widely. Imaging systems are based on various physical principles, with a sophistication which keeps enhancing (magnetic resonance imaging, thermography, multi and hyperspectral imaging). Beyond this heterogeneity of constitution, the resulting images share the property of being a support of information. In this context, we propose a contribution to informational approaches in imaging. This is especially guided by a transposition of Shannon's informational paradigm to imaging along two main directions. We present a joint-processing approach where the informational goal of the acquired images is a prior knowledge which is exploited in order to optimize some tuning configurations of the imaging systems. Different joint-processing problems are examined (joint observation scale - estimation, joint compression - estimation, and joint acquisition - compression). We then extend the field of stochastic resonance studies by exploring some new signal-noise mixtures enabling useful noise effects, in coherent imaging and in magnetic resonance imaging. Stochastic resonance is also considered for its specific informational significance (the noise useful to information), as a phenomenon allowing to test and further assess the properties and potentialities of entropic or informational measures applied to imaging. Stochastic resonance is especially used as a benchmark to confront such informational measures to psychovisual measures on images

Full textLow bit-rate can only be attained by lossy compression techniques. Most of the lossy compression schemes proceed by blocks at the transformation or at the quantization stage. The usual decompression algorithm is a symmetric inverse processing of the compression scheme. This generates blocking artifacts and ringing noise. Furthermore, decompressed image can never support post-processing such as edge detection. In this work, we propose a decompression scheme based on the theory of inverse problems. The decompression restores the compressed image with some constraints based on information about both the original image and on the compression procedure: the image smoothness and the upper bound of the quantization error, respectively. We consider an extension of the regularized mean square approach for ill-posed problems proposed by Miller. This idea is first carried out for the JPEG algorithm. We proposed two schemes. In the first one the dequantization array is calculated in order to minimize the reconstruction error subjected to a mean regularity constraint on the whole image blacks. This scheme is in full compliance with the JPEG standard. In the second approach the original image is pre-filtered by an unsharp masking filter in order to enhance the image details before compression and post-filtered by a low-pass inverse filter after decompression to remove the blocks. The inverse filter is designed for an optimal restoration subjected to both a constraint on the image roughness and on the decompression error. This second technique is more efficient than the first one against blocking artifacts. It is also in full compliance with the JPEG standard but requires two additional processing components. The robustness of the decompressed image to edge detection was assessed for both proposed schemes. We also proposed an algorithm which adapts the block size to the correlation length of the image in JPEG and which optimizes the coefficients of the quantization array. This approach is very efficient for medical images. The regularized restoration method is also applied to the subband coding techniques that use vector quantization of the subband images. Two approaches are considered. In the first one the image is restored at each resolution level and in the second one a global restoration is applied. Experimental results prove that both methods significantly reduce blocking effects and preserve the edges of compressed images. In order to complete the research, we compare the performance of our proposal to a non-linear approach which is adapted to the attenuation of ringing noise

Full textThis thesis aims at the dosimetry of high energy photon beams delivered to the patient during an external radiation therapy treatment. The objective of this work is to use EPID the Electronic Portal Imaging Device (EPID) in order to verify that the 3D absorbed dose distribution in the patient is consistent with the calculation performed on the Treatment Planning System (TPS). The acquisition is carried out in continuous mode with the aS-1200 amorphous silicon detector embedded on the TrueBeam STx machine (VARIAN Medical system, Palo Alto, USA) for 10MV photons with a 600 UM.min-1 dose rate. The source-detector distance (SDD) is 150 cm. After correction of the defective pixels, a calibration step is performed to convert the signal into an absorbed dose in water via a response function. Correction kernels are also used to take into account the difference in materials between EPID and water and to correct penumbra. A first model of backprojection was performed to reconstruct the absorbed dose distribution in a homogeneous medium by taking into account several phenomena: the scattered photons coming from the phantom to the EPID, the attenuation of the beams, the diffusion into the phantom, the build-up, and the effect of beam hardening with depth. The reconstructed dose is compared to the one calculated by the TPS with global gamma analysis (3% as the maximum dose difference criteria and 3mm as the distance to agreement criteria). The algorithm was tested on a homogeneous cylindrical phantom and a pelvis phantom for Intensity-Modulated Radiation Therapy (IMRT) and (Volumetric Arc Therapy (VMAT) technics. The model was then refined to take into account the heterogeneities in the medium by using radiological distances in a new dosimetrical approach better known as "in aqua vivo" (1). It has been tested on a thorax phantom and, in vivo on 10 patients treated for a prostate tumor from VMAT fields. Finally, the in aqua model was tested on the thorax phantom before and after making some modifications to evaluate the possibility of detecting errors that could affect the correct delivery of the dose to the patient.

Azzabou, Noura. "Variable Bandwidth Image Models for Texture-Preserving Enhancement of Natural Images." Paris Est, 2008. http://pastel.paristech.org/4041/01/ThesisNouraAzzabou.pdf.
Full textThis thesis is devoted to image enhancement and texture preservation issues. This task involves an image model that describes the characteristics of the recovered signal. Such a model is based on the definition of the pixels interaction that is often characterized by two aspects (i) the photometric similarity between pixels (ii) the spatial distance between them that can be compared to a given scale. The first part of the thesis, introduces novel non-parametric image models towards more appropriate and adaptive image description using variable bandwidth approximations driven from a soft classification in the image. The second part introduces alternative means to model observations dependencies from geometric point of view. This is done through statistical modeling of co-occurrence between observations and the use of multiple hypotheses testing and particle filters. The last part is devoted to novel adaptive means for spatial bandwidth selection and more efficient tools to capture photometric relationships between observations. The thesis concludes with providing other application fields of the last technique towards proving its flexibility toward various problem requirements
