基于光照补偿与金字塔融合的水下图像增强方法
Underwater Image Enhancement Method Based on Illumination Compensation and Pyramid-Based Blending
摘要
Abstract
The existing enhancement methods based on deep learning and underwater imaging quality degradation models still suffer from poor robustness due to color deviation,scattering-induced blur,and uneven brightness in underwater optical imaging.In response to these issues,this article proposed a single image-based enhancement method for underwater imaging,which combined illumination compensation and pyramid-based detail blending.First,based on global illumination and color channel characteristics,illumination intensity at the pixel level was estimated and compensated,achieving intensity correction for each color channel.Next,the scatter components of the image were estimated using Gaussian blur,and a multi-scale Gaussian filter residual method was used for descattering.Finally,a multi-image pyramid-based detail blending technique was proposed,combining edge enhancement,adaptive Gamma correction,and brightness equalization.This method effectively preserved image details while addressing uneven brightness.Compared to existing techniques,this method featured improved adaptability and achieved better performance in underwater image quality measures(UIQMs)and underwater image color and quality evaluation(UCIQE)measures.关键词
