| Abstract: | Image compression coding technique of DCT and RLE is introduced respectively in this paper. Moreover DCT and RLE mixed lossy compression mothod is intuitively discussed on the application of gray image compression, which based on the experiment in the environment of mathematical analysis tools of Matlab. The result of numerical experiment shows that this method not only has the advantages such as simple, fast speed and small errors, but also can further to improve the efficiency and precision of image compr... |
