| Abstract: | Image compression coding technology is the key technolagies of the morden media and communications. Discrete Cosine Transform has been widely used in the areas such as image compression,especially in the JPEG and the MPEG,because of its good energy compaction properties and fast algorithm. The papers introduce the core of DCT coding,and use the matlab language to achieve the DCT-based image compression. |
