摘要：
In order to improve the visual effect of the image, improve the peak signal-to-noise ratio and the structural similarity index of the image, and make the image more meet the visual requirements of the human eye, an edge color enhancement method based on the CANNY operator is proposed. The sparse representation method is used to achieve image denoising, the 2x2 filter is improved, the first-order partial derivative of the two-dimensional Gaussian function is established, and the image edge is detected to obtain accurate image edge information; According to Retinex theory, implement image color distortion recovery and image block effect removal, establish Lab color space, perform enhancement processing on luminance channel, and realize edge color enhancement of artistic image. The experimental results show that the peak signal-to-noise ratio, structural similarity index and CCI value of the method in this paper are high, and the LOE value is low, and the visual effect after image enhancement has been significantly improved, indicating that the enhancement effect is in line with human vision.
