A General Model for Low-Illumination Video Enhancement

Abstract:

In order to improve the visual effect of different regions within a video frame, in this paper, we propose a general and effective enhancement model for low-illumination video. The proposed method firstly is to change color space from RGB to HSI color space, Then enhance the I channel by nonlinear tone-mapping function. At the same time, in order to reduce the color distortion, we enhance the saturation component S. Finally, color image is reconstructed. Experimental results show the effectiveness and robustness.
