摘要
Abstract
In order to evaluate the real-time clarity of video images,a new image clarity algorithm is designed and implemented on Xilinx A-7 FPGA chip.Firstly,a state machine design OTSU algorithm is used to calculate the adaptive threshold of the image to separate ed-ges.Secondly,parallel processing and pipeline implementation are applied to improve the computational clarity of the 4-direction Tenen-grad gradient function.The experiment results indicate that the design can complete 640X480@30 fps evaluation of the clarity of video stream images in 66 ms,with a certain degree of sensitivity.关键词
