   University essay from Datorteknik

   Author : Lang Yu; [2010]
   Keywords : Video Surveillance; JPEG XR; Encoder; SoC; Evaluation; PSNR; Compression Ratio; Implementation; PCT; Quantization; Adaptive Prediction; Adaptive Entropy Coding;

   Abstract : This report describes both evaluation and implementation of the new coming image compression standard JPEG XR. The intention is to determine if JPEG XR is an appropriate standard for IP based video surveillance purposes. Video surveillance, especially IP based video surveillance, currently has an increasing role in the security market. READ MORE

3. 2. A study of CABAC hardware acceleration with configurability in multi-standard media processing

   University essay from Institutionen för systemteknik

   Author : Oskar Flordal; [2005]
   Keywords : CABAC; Arithmetic coding; H.264; JPEG 2000; instruction level optimizing; accelerators; assembler; VLC; encoder; hardware reuse; profiling; DSP; multimedia;

   Abstract : To achieve greater compression ratios new video and image CODECs like H.264 and JPEG 2000 take advantage of Context adaptive binary arithmetic coding. As it contains computationally heavy algorithms, fast implementations have to be made when they are performed on large amount of data such as compressing high resolution formats like HDTV. READ MORE
