ABSTRACT
Abstract: in order to improve the performance of traditional sports teaching video compression algorithm, this paper selects spatial KL transform technology and GPCA segmentation technology as research tools, and proposes a new video compression algorithm. The diamond search method is introduced in the algorithm, and the resolution of video frame is completed efficiently. After XL transformation, the minimum error is determined. The test results show that the proposed algorithm not only has high SNR and more compressed frames, but also has high definition and compression efficiency.

Rate-distortion based temporal filtering for video compression
DCC '96: Proceedings of the Conference on Data CompressionWe consider the temporal DPCM loop at the heart of most modern high performance video coders. Targeting low bitrate-low complexity video applications, it is shown that DPCM is inefficient in this region. The DPCM codec is analyzed in the low bitrate ...
Rate conversion of MPEG coded video by re-quantization process
ICIP '95: Proceedings of the 1995 International Conference on Image Processing (Vol. 3)-Volume 3 - Volume 3We propose rate conversion method by re-quantization in which MPEG coded video at high bit rate is converted into the MPEG bitstream at a lower bit rate without decoding to obtain the reconstructed picture. The quantization step required for re-...
HEVC intra mode selection based on Rate Distortion (RD) cost and Sum of Absolute Difference (SAD)
The relationship between SAD and RD-cost is investigated for intra mode selection.The 'rate' and 'distortion' requirement for a given SAD value varies with the QP.The model is derived that is based on the rate and distortion requirement for SAD.The ...
