It is important because of its impact on the evapotranspiration and irrigation management. The most widespread approach is based on the synergy between radar and optical data to retrieve soil moisture. The aim is to study the potential of Sentinel sensors (Sentinel-1 (S-1) and Sentinel-2 (S-2)) for the retrieving of the soil moisture at regional scale. First, an analysis between the radar (S-1) and the measured data (soil moisture, soil roughness and Leaf Area Index (LAI)) is established over bare soils and cereal fields in the Kairouan plain, Tunisia. The results of the sensitivity analysis show that the radar signal in VV (vertical) polarization and soil and vegetation parameters are strongly correlated than in VH cross-polarization. The Water Cloud Model was calibrated using the NDVI (Normalized Difference Vegetation Index) retrieved from Sentinel-2 images. Then, an inversion approach of this model is developed for the mapping of soil moisture at high spatial resolution.","PeriodicalId":332253,"journal":{"name":"2018 4th International Conference on Advanced Technologies for Signal and Image Processing (ATSIP)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130186779","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}

It has two advantages: first, it uses a wide frequency spectrum and second, it offers an intrinsic security dimension since the light cannot pass through walls. We present a cost-effective and energy-efficient system based on VLC for video transmission. Our system could be easily implemented without introducing major modifications to the existing infrastructure. This system does not entail special devices, nor does it require installing drivers. We overcome three main research challenges: 1) removing the noise caused by the ambient light and recovering data, 2) reaching transmission debit enabling high-quality video running fluidly, 3) establishing a distance between the transmitter and the receiver long enough to facilitate the use of the system in real conditions. We implemented a visible light communication prototype operating at 4 Mb/s capable of exceeding a distance of 2 meters. The transmitter is based on a regular white LED. Due to its nanosecond response and high sensitivity to light, the photodiode PD is the main component of the receiver. The system is based on an On-Off keying modulation and demodulation technique. A cyclic redundancy check (CRC) is implemented within the developed software to reduce the bit error rate (BER)._This communication technology can be implemented where radio frequency communication cannot, for example, in hospitals. In perspective, we intend to make progress at the software-level to enable realtime video transmission.","PeriodicalId":332253,"journal":{"name":"2018 4th International Conference on Advanced Technologies for Signal and Image Processing (ATSIP)","volume":"321 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124538624","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}

It involves five DCT/DST-based transform types known as: DCT-II, DCT-VIII, DCT-V, DST-I and DST-VII. This work, proposes multiplierless hardware architectures of size 4 for all considered transform types. These architectures are implemented in FPGA benefitting from both correlation and symmetry properties of the matrices coefficients. This paper presents and compares two different architecture aspects without and with involving state-machines to evaluate their effect on the proposed hardware design. The experimental and synthesis results show that the two methods, supporting all five transform types, require less than 3% of the offered FPGA device area and provide respectively 318 MHz and 285 MHz as maximum operation frequency. With adding the pipelining operation, the proposed designs can support real time coding of 4Kp30 and 2Kp60 videos, respectively. Moreover, the implementation based on state-machines offers about 45% operations number and hardware area reduction.","PeriodicalId":332253,"journal":{"name":"2018 4th International Conference on Advanced Technologies for Signal and Image Processing (ATSIP)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115287979","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}
