Full textThe explosion of multimedia applications is largely due to the efficiency of the compression techniques used. H. 264/AVC, also known as MPEG-4 Part 10 is the newest video coding standard. It is more effective than previous standards (MPEG1, MPEG2, part 4, H26x…) and achieves significant compression gains. As for other standards, the rate control is a key element of H. 264/AVC because it helps to regulate the visual quality of the reconstructed sequence while respecting the bandwidth constraints imposed by the channel transmission. In accordance with the specified target bit-rate, the rate control algorithm determines appropriately the quantization parameters. Basically, a first Rate-Quantization function elaborates a relationship between the rate and the quantization parameter (QP). A second function called Distortion-Quantization estimates the distortion (or quality) of the reconstructed video based on the used quantization parameter. These two functions lead together to a relationship (usually quadratic) between the quantization parameter, the target number of bits and the basic unit (Frame, Slice, macroblock or set of macroblocks) statistics. These functions have been the subject of several studies. The models that have been adopted and therefore recommended by the group standardization, do not generally offer better performances and they are far from optimal. This thesis is in this context. Its main objective is to develop and design new techniques to improve the performance of the rate control algorithm and those of the H. 264/AVC standard. These techniques are based on both a detailed analysis of the major current limitations and a wide literature review. Our purpose is to provide a more appropriate determination of the quantization parameter, a selective bit allocation that integrates Human Visual System properties and enhances the reconstructed video quality. To determine accurately the quantization parameter, two Rate-Quantization models (R-Q) have been proposed. The first model designed for Intra-Frames, is a non-linear one. It is used to determine the optimal initial quantization parameter, while exploiting the relationship between the target bit-rate and the complexity of Intra-Frames. The second model is a logarithmic one and it is designed for Inter coding units. It replaces the two models used by the H. 264/AVC rate controller and reduces the computational complexity. The frame layer bit allocation of the H. 264/AVC baseline profile remains basic. It assumes that GOPs (Groups Of Pictures) have similar characteristics and the target number of bits are fairly allocated to coding units regardless of their complexity. For a more accurate bit allocation, a new model has been proposed including two complexity measures. The first is a motion ratio determined from the actual bits used to encode the previous frames. The second measure uses the difference between adjacent frames and the histogram of this difference. Finally, to better control the visual quality of the reconstructed video, a saliency map is included into the bit allocation process. The saliency map generated by a bottom-up approach, simulates the human visual attention. It has been used to adjust the quantization parameter at frame layer. This adjustment allows the assignment of more bits to frames containing more salient regions (supposed to be more important than others). At macroblock layer, the saliency map is exploited to efficiently allocate the number of bits among the macroblocks of the same frame. This bit repartition by ''region'' of interest improves the visual quality of the frame. Experimental simulations show that the proposed models, when compared with two recent algorithms of rate control (JVT-O016 and JM15. 0), improve significantly the coding performances in terms of average bit-rates and PSNR. More consistent quality and therefore a quality smoothness through frames is also observed

Full textCytotoxic lymphocytes rely on actin cytoskeleton remodeling to achieve their function. In particular cytotoxic T lymphocytes and NK cells assemble the immunological synapse (IS), a complex actin-rich structure that allows the interaction with target cells, such as infected cells or tumor cells, and permits the polarized delivery of lytic granules. Although actin cytoskeleton remodeling is known to be a driving force of IS assembly and dynamics, our understanding of the molecular control of actin remodeling sustaining IS dynamics remains fragmented. This PhD project consisted in developing a high-content imaging approach to unbiasedly define the metrics of IS from human T and NK lymphocytes and to characterize the requirements for actin cytoskeleton integrity in organizing the IS architecture.For that purpose, the stimulation and staining of cell lines and primary cells in multiwell plates and acquisition of a unique set of >100.000 confocal images with a fully automatized high-content imager was optimized. The images were analyzed with two complementary CellProfiler analytical pipelines to characterize the morphological features associated with different treatments and disease status. We first extracted 16 morphological features pertaining to F-actin, LFA-1 or lytic molecules based on prior knowledge of IS assembly, and included features pertaining to the nucleus. We show that IS assembly in Jurkat and NK-92 cells is characterized by increased F-actin intensity and cell area. For Jurkat cells, we report an increase in LFA-1 intensity and surface area, and for NK-92 cells an increase in lytic granule detection at the IS plane. We then treated NK-92 cells with seven drugs known to affect different aspects of actin dynamics and investigated the associated effects on IS features. We report concentration dependent effects, not only on F-actin intensity, as expected, but also on lytic granule polarization. Furthermore, using a high-resolution morphological profiling based on >300 features, we show that each drug inflicts distinct alterations of IS morphology. In a next step, we applied our experimental pipeline to primary NK cells isolated from the blood of healthy donors. Distinct morphological features were characterized among the NK cells from different donors, highlighting the sensitivity of our approach, but also revealing an unsuspected variability of immune cell morphologies among donors. We then further applied our approach to primary CD8+ T cells from patients with a rare immunodeficiency due to mutations in the gene encoding the actin regulator ARPC1B. ARPC1B deficiency results in decreased F-actin intensity, as well as in lytic granule polarization. This prompted us to assess the ability of these cells to kill target cells, which was markedly reduced. These results illustrate how the systematic analysis of the IS might be used to assist the exploration of fonctional defects of lymphocyte populations in pathological settings. In conclusion, our study reveals that although assembly of the IS can be characterized by a few features such as F-actin intensity and cell spreading, capturing fine alterations of that complex structure that arise from cytoskeleton dysregulation requires a high-content analysis. The pipeline we developed through this project holds promises for the morphological profiling of lymphocytes from primary immunodeficiency patients whose genetic defect has not yet been identified. Moreover, the discriminative power of our high-content approach could be exploited to characterize the response of lymphocytes to various stimuli and to monitor lymphocyte activation in multiple immune-related pathologies and treatment settings

Full textThe Non-Binary Low Density Parity Check (NB-LDPC) codes constitutes an interesting category of error correction codes, and are well known to outperform their binary counterparts. However, their non-binary nature makes their decoding process of higher complexity. This PhD thesis aims at proposing new decoding algorithms for NB-LDPC codes that will be shaping the resultant hardware architectures expected to be of low complexity and high throughput rate. The first contribution of this thesis is to reduce the complexity of the Check Node (CN) by minimizing the number of messages being processed. This is done thanks to a pre-sorting process that sorts the messages intending to enter the CN based on their reliability values, where the less likely messages will be omitted and consequently their dedicated hardware part will be simply removed. This reliability-based sorting enabling the processing of only the highly reliable messages induces a high reduction of the hardware complexity of the NB-LDPC decoder. Clearly, this hardware reduction must come at no significant performance degradation. A new Hybrid architectural CN model (H-CN) combining two state-of-the-art algorithms - Forward-Backward CN (FB-CN) and Syndrome Based CN (SB-CN) - has been proposed. This hybrid model permits to effectively exploit the advantages of pre-sorting. This thesis proposes also new methods to perform the Variable Node (VN) processing in the context of pre-sorting-based architecture. Different examples of implementation of NB-LDPC codes defined over GF(64) and GF(256) are presented. For decoder to run faster, it must become parallel. From this perspective, we have proposed a new efficient parallel decoder architecture for a 5/6 rate NB-LDPC code defined over GF(64). This architecture is characterized by its fully parallel CN architecture receiving all the input messages in only one clock cycle. The proposed new methodology of parallel implementation of NB-LDPC decoders constitutes a new vein in the hardware conception of ultra-high throughput rate decoders. Finally, since the NB-LDPC decoders requires the implementation of a sorting function to extract P minimum values among a list of size Ns, a chapter is dedicated to this problematic where an original architecture called First-Then-Second-Extrema-Selection (FTSES) has been proposed
