For this aim, the main idea consists in embedding an information in the digital media with good properties in terms of robustness, capacity and invisibility (perceptual transparency and statistical undetectability). Recent studies has highlighted the importance of statistical undetectability which is unfortunately not often evaluated. We propose in this work to study a watermarking scheme with side-information at the encoder and based on Treillis Coded Quantization (TCQ). The main particularity of our approach is that we propose to apply the embedding process in an independent domain (by the way of Independent Component Analysis: ICA). We then show the improvement of the robustness and statistical undetectability properties with our proposal. The comparison with well known watermarking approaches, of the performances obtained, is done. This highlight the wide improvement of the obtained performances: high robustness without reducing the capacity, good security level or very low distorsions on the watermarked signals probability density functions.","PeriodicalId":343415,"journal":{"name":"International Workshop on Systems, Signal Processing and their Applications, WOSSPA","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124558393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After careful study and analysis of this filter, we have concluded that its complexity lies in the data dependency and in the control module of elementary filters that compose it, but not in the type of these filters. In this paper, we propose two hardware implementations for the deblocking filter using the same strategy for memory management. The implementations differ on the utilized data width. The first one utilizes 32-bit while the second one utilizes 128-bit. The use of 128-bit data width is in order to ensure a high degree of parallelism and to avoid the use of transpose circuits and the intermediate buffers between the elementary modules in the filter. Simulation and synthesis results are then compared. The number of consumed LUTs remains almost the same compared with previous implementations and the number of clock cycles required to process a macroblock is reduced about 40% less than the best of the competing proposals.","PeriodicalId":343415,"journal":{"name":"International Workshop on Systems, Signal Processing and their Applications, WOSSPA","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123683107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The modeling of the global system components is developed with the integration of inverter with filter. The model of the solar generating subsystem is particularly developed. It is shown that this model is interesting for analyzing the dynamic behavior of the system and for designing the control strategy. The operating point of a photovoltaic generator that is connected to a permanent magnet synchronous motor is determined by the intersection point of its characteristic curves. In general, this point is not the same as the generator's maximum power point. This difference means losses in the system performance. Other point developed in this paper is presents an improved maximum power point tracking (MPPT) algorithm of a PV system under real climatic conditions. The proposed MPPT is based on the perturbation and observation (P&O) strategy and the variable step method that control the load voltage to ensure optimal operating points of a PV system.","PeriodicalId":343415,"journal":{"name":"International Workshop on Systems, Signal Processing and their Applications, WOSSPA","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130451119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
