Acceleration of Histogram-Based Contrast Enhancement via Selective Downsampling

14 Sep 2017Gang CaoHuawei TianLifang YuXianglin HuangYongbin Wang

In this paper, we propose a general framework to accelerate the universal histogram-based image contrast enhancement (CE) algorithms. Both spatial and gray-level selective down- sampling of digital images are adopted to decrease computational cost, while the visual quality of enhanced images is still preserved and without apparent degradation...
