A Novel Image Enhancement Method based on Visual Saliency Detection

Abstract

We present a novel image enhancement method based on the visual saliency detection model. This is a two-stage method including visual saliency detection and salient detail enhancement. In general, visual salient regions of the image will be detected first. Then, unsharp masking technique with different enhancement weights is applied to salient and non-salient regions respectively. Both of the visual experimental results and objective measurement reveal that this proposed method can enhance the image with much less noise-amplification and over-enhancement problems.
