But for its high difficulty of coding and decoding algorithm and low throughput  optimization RS algorithm is always studied as one of the focus in the error-correction field. A new coding method  parallel coding and decoding data into groups in lower step finite field for avoiding complex matrix iteration and Chien search computation  is proposed in this paper. It is proved that the coding and decoding throughput of the parallel grouping RS coder is increased and the hardware complexity is reduced with changeless error-correction capability from the simulation results using ModelSim SE 6.0 and synthetic results using ISE 9.11. 2010 IEEE.   a scalable encryption scheme for ccsds image data compression standard 会议论文  OAI收割 2010 IEEE International Conference on Information Theory and Information Security, ICITIS 2010, Beijing, 40878 Mingyu Li; Xiaowei Yi; Hengtai Ma   |  收藏  |  浏览/下载：26/0  |  提交时间：2011/03/31 CCSDS image data compression standard  ciphertext bitstream  end-to-end security  low-complexity transparent transcoding  near rate-distortion  packet header  scalable encryption scheme  truncation points  cryptography  data compression  image coding  transcoding   Complexity-constrained h.264 video encoding 期刊论文  iSwitch采集 Ieee transactions on circuits and systems for video technology, 2009, 卷号: 19, 期号: 4, 页码: 477-490 作者:  Su, Li;  Lu, Yan;  Wu, Feng;  Li, Shipeng;  Gao, Wen 收藏  |  浏览/下载：27/0  |  提交时间：2019/05/10 Complexity control  H.264/avc  Power consumption  Real-time video coding   Low-complexity quantization for h.264/avc 期刊论文  iSwitch采集 Journal of real-time image processing, 2009, 卷号: 4, 期号: 1, 页码: 3-12 作者:  Zhang, Yun;  Jiang, Gangyi;  Yu, Mei 收藏  |  浏览/下载：21/0  |  提交时间：2019/05/10 H.264/avc video coding  Integer transform  Quantization  Low-complexity   Low-complexity quantization for H.264/AVC 期刊论文  OAI收割 JOURNAL OF REAL-TIME IMAGE PROCESSING, 2009, 卷号: 4, 期号: 1, 页码: 3-12 作者:  Zhang, Yun;  Jiang, Gangyi;  Yu, Mei   |  收藏  |  浏览/下载：14/0  |  提交时间：2019/12/16 H.264/AVC video coding  Integer transform  Quantization  Low-complexity   An image matching algorithm based on sub-block coding (EI CONFERENCE) 会议论文  OAI收割 2nd International Workshop on Computer Science and Engineering, WCSE 2009, October 28, 2009 - October 30, 2009, Qingdao, China 作者:  Li S. 收藏  |  浏览/下载：34/0  |  提交时间：2013/03/25 In order to improve the speed of matching algorithm and simplify the processing of existing sub-block coding matching  a new template matching method combined local gray value encoding matching and phase correlation is proposed. Matching process is divided into rough matching and fine matching. Rough matching divides the image into certain size blocks called R-block  sums the gray value of each R-block pixel  encodes the R-block according to the gray value distribution of R-block with the adjacent R-block  and matches by step between the template and each search sub-image. Then  fine matching results are obtained using phase correlation according to initial match parameters. The time complexity of the proposed method is (M2) .The new algorithm is faster than traditional algorithm by two orders of magnitude  and the speed has improved twice compared with existing sub-block coding method. Experiments demonstrate that the new algorithm is robust to the linear transformation of pixel grey value and image noise  and it also has the stability of small-angle rotation. 2009 IEEE.
