Color image enhancement using histogram equalization method without changing hue and saturation
Su‐Ling Lee, Chien‐Cheng Tseng · 2017
In this paper, a color image enhancement method is presented by using intensity histogram equalization (HE) approach without changing hue and saturation in HSI color space. The proposed method has better visual colorfulness than the conventional HE method because hue and saturation are preserved in the enhancement process. The back-lighting image and night-time image are used to demonstrate the effectiveness of the proposed color image enhancement method.
