| Abstract: | Firstly, This paper introduces some important aspects on choosing wavelet basis when using wavelet transform to perform image compression, and shows the different effects of different wavelet basis on image compression of BMP type by experiment data. Secondly, The EZW and SPIHT are the representative methods of embedded image coding algorithms based on wavelet transform. In this paper, their main principle is analysed and compared, and the performance of EZW algorithm is analysed and improved by experiment. |
