Advanced DCT-based video encoding method and apparatus

摘要

An improved motion image encoding method is based on a discrete cosine transform (DCT)-based motion image encoding method that uses a plurality of modified quantization weight matrices, the method including selecting one of the plurality of modified quantization weight matrices based on noise information from input image data, performing DCT on the input image data, and performing quantization on the DCT input image data using the selected modified quantization weight matrix. <IMAGE>
