JPEG2000 is becoming one of primary techniques of data compression gradually. Now JPEG2000 as a standard of new static image compression, is deemed to a perfect resolvent of image coding which is applied in Internet and Wireless: connect, and it distinctly precedes traditional static image compression arithmetic at various aspect. In this text, we summarily present the theory and advantages of JPEG2000 and wavelet transform theory firstly. Secondly we particularly depict JPEG2000' s key technique which is wavelet transform and EZW coding arithmetic, and do wavelet transform with second wavelet which is realization by lifting scheme. And we illuminate the process of wavelet transform and EZW arithmetic with two examples. At last we achieve wavelet transform and EZW arithmetic using C++ language, according to this program we can accomplish image' s coding and decoding with TMS320C6701 real time. Through five times code and decode with this program, we can obtain good quality retrieval image and it' s compression proportion reaches 25:1. |
