Title: Fast Image Compression Algorithm Based on Wavelet Transform
Abstract: In this paper,the widely used embedded wavelet zerotree coding(EZW) and set partitioning in hierarchical trees algorithm(SPIHT),proposed a wavelet transform for image enhancement algorithm for high-frequency compression.The concept of interval changes is introducted in the matrix of wavelet transform,replaced with the approximate value of the coefficients of wavelet transform,and then encoding and transmission.After the wavelet transform for image,it used the DPCM algorithm in low-frequency part,and used the proposed algorithm in the high frequency part,then compression can be used in a short period of time to keep most of the energy of the original image.Although this algorithm compared with the original lost two parts of fidelity,it reduced the complexity of the algorithm and the encoding time.It is very advantageous to compress a significant image and transmission.The results show that proposed Fast compression algorithm based on wavelet transform to obtain a more satisfactory result.
