Hardware Circuit Design for La Gell 5/3 Wavelet Transform Based on FPGA
摘要
Abstract
In order to compress the redundant image data effectively, this paper put forwards a fast wavelet transform project based on FPGA. The principle of La Gell 5/3 wavelet transform is introduced, and an appropriate wavelet transform hardware circuit of La Gell 5/3 wavelet transform is designed for the high frame rate CMOS camera. This design is programmed on the QuartusII software platform in Verilog hardware language. The feasibility of the algorithm is verified by comparing the original image to inverse transformed image, which is transformed by Matlab. The experimental result shows that this program successfully realized the three-level fast wavelet transform for a given image through the system of La Gell 5/3 lifting wavelet transform which based on FPGA, and the plan is more suitable for application of real-time high-speed image processing by compared to other hardware circuit such as DSP.关键词
