A Novel Image Contrast Restoration Algorithm for Fog
Hui Xian Lv, Zhi Gang Zhao, Yan Feng Xu · Advanced materials research · 2013
Images captured in fog suffer from low contrast, restoration of fog- degraded images are needed. In this paper, a novel algorithm of image restoration based on wavelet semi-soft threshold is presented. The results show detail restoration and de-noising are improved effectively comparing with Histogram equalization and homomorphic filtering method. It can be concluded that the new algorithm enhanced the contrast of fog-degraded image well.
