查询词典 compression

To improve the transmission efficiency and reduce the storage requirement, efficient encoding algorithms should be used to remove the residual information in images, and fewer bits should be used to describe images on restrictions of given distortion. Vector quantization is an efficient lossy compression technique, whose prominent virtues are high compression ratio and simple decoding process, so it has become one of important compression techniques for image coding.
