| Abstract: | Discrete cosine transform （DCT） is one kind of mapping transformation methods, which is implcmented by transforming the pixels of the image from one space into another space for the purpose of image compression. This paper researches on the image compressing method in DcT. Then, the basic principle and implementation steps for image compressing based on DCT have been given. In order to do this research, a software is designed for image compressing by VC＋＋ technology. Through this software, DCT compression can be realized. Finally, some image compression results and their corresponding data are given in the paper. |
