The Study Of Image Compression Based On Wavelet Transform

With the rapid development of multimedia technology and network communications, it is necessary to have better performance of image compression method for image transmission and storage. And after the new image compression standard JPEG2000 came out, image compression based on wavelet has further researches and development. In the mean time, image database is widely used in many fields, which requires different image compression technologies according to special characteristics of images as well. The research subject of this paper is put forward for this background and the requirements of lab's projects. This paper contains these parts as follows:Part 1: this thesis first reviews some basic conception, nowadays researches about image compression, the background of this paper and my main work. Then some academic theory about wavelet is presented, which contains wavelet, discrete wavelet, DWT transformation. And after that the key arithmetic of JPEG2000 is introduced, compared with JPEG standard.Part 2: in this part the application of wavelet transform in image...
