Abstract

In this paper, we propose a novel scheme of Local Histogram Equalization (LHE) using guided image filter. The sub-blocks are segmented from the input image, after which we individually compute each local histogram used for multiple transformation functions. To further remove the block artifacts caused by LHE, we employ the input image to guide the texture information, while keeping the enhancement effect of the local contrast. Experimental results show that our proposed scheme produce the high visual effects on the enhanced images being much better than other HE-based methods.
