一种新的低照度彩色图像增强算法
New low illumination color image enhancement algorithm
摘要
Abstract
In order to avoid the color distortion during the image enhancement, this paper proposed a new low illumination color image enhancement method combining the saturation enhancement with segment logarithmic transformation and value en hancement with edge retaining( S_ Iog-V_edge) based on the multi-scale Retinex (MSR) algorithm without changing the hue in the HSV color space. Results show that this method can improve the low illumination images' visual effect and enhance the image brightness and contrast while retaining the image hue and edge. The 25 low illumination images average value, standard deviation and contrast incremental value are increased by 94.95% ,20. 93% and 29. 88% individually,the entropy and con trast incremental value are 7. 34% and 151.51% more than the multi-scale Retinex with color restoration ( MSRCR) .showing the effects are better than Retinex methods.关键词
