换在压缩效率、还原图像质量上具有更大的优越性
For the increasingly progressive image transform coding techniques have been incorporated into the current MPEG 4 and JPEG2000 coding standard discrete wavelet transform digital image coding principle and hardware implementation are reviewed introduction. In analyzing wavelet transform algorithm based on fast, focused on the past 10 years, the proposed hardware implementation of a variety of discrete wavelet transform the typical structure of the hardware resources and the processing speed of two aspects of the comparison. For the transformed coefficient quantization, summarizes several based EZW coding algorithm to compare the peak signal to noise ratio and encoding time. Compared to the discrete cosine transform image coding, using discrete wavelet transform in compression efficiency, reducing image quality advantages of a greater (2013-10-19, PDF, 337KB, 下载4次)
