基于改进Retinex的图像增强算法
Image enhancement algorithm based on improved Retinex
摘要
Abstract
In order to improve the effect of image enhancement,a new image enhancement algorithm based on improved Retinex is proposed. In this algorithm,the original image is decomposed by the multi-scale Retinex ( MSR ) algorithm to obtain the illumination component and the reflection component. The image is processed by the gamma ray transform and modified by a linear stretching method while the reflection component image is processed using the bilateral filtering algorithm. The light component and the reflection component of images are combined to obtain the enhanced image, and the performance is tested by the simulation experiments. The experimental results show that the proposed image enhancement algorithm can improve the visual quality of images, retain more abundant details, effectively eliminating the "halo artifacts"and being more conducive to the subsequent image processing.关键词
