自适应色彩补偿和多尺度融合的水下图像增强
Adaptive color compensation and multi-scale fusion for underwater image enhancement
摘要
Abstract
To address the challenges of color distortion,uneven lighting,low contrast,and blurred details in underwater images,an adaptive color compensation and multi-scale fusion enhancement algorithm is proposed.Initially,adaptive color compensation and white light balance algorithms are employed to cor-rect the image colors.Subsequently,adaptive gamma correction is applied to the color-corrected images to achieve uniform illumination.Thereafter,the uniformly lit images undergo processing through adaptive Rayleigh histogram stretching and adaptive unsharp masking to enhance contrast and detail.Finally,non-downsampling contour wave fusion is utilized to further refine the quality of the images with improved con-trast and enhanced details.Experimental results demonstrate that the proposed algorithm effectively cor-rects the colors of underwater images and significantly enhances their contrast and clarity,with average evaluation metrics PSNR,SSIM,IE,and UCIQE showing increases of 43.52%,58.65%,12.5%,and 32.13%,respectively,compared to the original images.This algorithm is shown to substantially im-prove underwater image quality.关键词
