| Abstract: | This paper studied the principle of the 5/3 wavelet transform algorithm of digital image and the VLSI hardware structure of the 5/3 wavelet transform algorithm has been designed. According to the distributing characteristic of the parameters of 5/3 wavelet transform algorithm, the hardware implementation of the algorithm is simplified. The system has been implemented on FPGA after synthesis and simulation. Experiment result shows that this improved hardware design succeeds in arriving at the goal of high sp... |
