Behind the Structure of Video VQ-Coder
Аннотации
This paper introduces an implementation and structure of a video codec (coder-decoder) using Vector Quantization (VQ) in the program Matlab. It also aims on the VQ weak and strong features and it describes an experiment with turning the advantages into concrete profit in video data compression. We would like to aim also on usage in video MPEG 4 (Motion Picture Experts Group) standard or in compressing the scientific (high resolution) images. In conclusion we are comparing our approach with other image compression methods with objective and subjective criteria of image quality perception.
