| Abstract: | This paper focuses on the research of the image compression system of the international standard JPEG 2000 and analyzes how the compression algorithm based on the discrete wavelet transforms implements compression, coding, transmission and storage of still images. This paper also deals with the development of the JWlet experimental software and applies the JWlet software to make presentation and evaluation of the compressed images. It is proved that the wavelet based image compression system has many perfect features such as progressive transmission, region of interest and error resilience and etc. as well as considerable compression efficiency. |
