基于加权引导滤波的水下图像增强算法
Underwater image enhancement algorithm based on weighted guided filter
摘要
Abstract
In order to solve the problem of low contrast,large noise of underwater images,an underwater image enhancement algorithm based on weighted guided filter is proposed.The algorithm improves image contrast by CLAHE.Then the edge-aware weighting of weighted guided filter is accurately calculated by Canny algorithm instead of variance.The enhancement image is denoised with weighted guided filter and the saturation and value components of the denoised image are locally en-hanced.The experimental results show that the image noises are suppressed effectively,the structural similarity of enhanced images is improved.Besides,the enhanced images have high contrast and good visibility.关键词
