Subjective Evaluation of Hevc Intra Coding for Still Image Compression
High Efficiency Video Coding (HEVC) demonstrates a significant improvement in compression efficiency compared to H.264/MPEG-4 AVC, especially for video with resolution beyond HD, such as 4K UHDTV. One advantage of HEVC is the improved intra coding of video frames. Hence, it is natural to question how such intra coding compares to state of the art compression codecs for still images. This paper ...
متن کاملMultiresolutional/fractal Compression of Still and Moving Pictures
The scope of the present dissertation is a deep lossy compression of still and moving grayscale pictures while maintaining their fidelity, with a specific goal of creating a working prototype of a software system for use in low bandwidth transmission of still satellite imagery and weather briefings with the best preservation of features considered important by the end user. Among the major resu...
متن کاملDifferential Pixel Value Coding for HEVC Lossless Compression
High efficiency video coding (HEVC) [1] is a new video coding standard developed by Joint Collaborative Team on Video Coding (JCT-VC) of ITU-T Video Coding Experts Group (VCEG) and ISO/IEC Moving Picture Experts Group (MPEG). Currently, most of coding techniques are established and HEVC version 1 will be released in January 2013 [2]. We ex‐ pect that HEVC is widely used in various applications ...
متن کاملEvaluation and Performance Comparison between JPEG2000 and SVC
The scalable extension to the H.264/AVC has been established as a scalable video coding (SVC) standard, and JPEG2000 is a state of the act still image coding standard. The most distinctive difference between SVC and JPEG2000 is, in terms of spatialfrequency transformation, that SVC is based on the Discrete Cosine Transform (DCT) and JPEG2000 is based on Discrete Wavelet Transform (DWT). JPEG200...
