ABSTRACT
In this paper, the four morphological operator’s erosion,dilation, opening and closing are used to detect thebackground. After the background is extracted, contrast ofbad lightning image is improved by the application ofoperators based on Weber’s law notion Two contrastenhancement operators Block Analysis method andOpening by Reconstruction method are used. Theseoperators avoid abrupt changes in intensity among differentregions .In the final step, we enhance the image by usingvarious filtering techniques. By applying filteringtechniques, our image will be of good contrast and freefrom bad lightning.
