Adaptive Video Image Enhancement Algorithm Based on FPGA Design

Abstract:

Aiming at the problem of image quality degradation due to scenes change rapidly, an image enhancement algorithm based on scene intelligent identification is proposed. The algorithm sharpen the image detail by using Laplace operator. Determines the change image scene according to the gray value, constructs different gray mapping function, and adjusts gray value range of image adaptively to improve the contrast ratio of image enhancement. By using parallel processing, the algorithm has high execution efficiency, so it can meet the real-time processing of HD video. Experimental result shows that the proposed algorithm has satisfying performance in the rapidly change scene.
