Improvement of contrast of images in Poor Light: a Research and Analysis
Journal Title: International Journal of Computer Science and Management Studies (IJCSMS) www.ijcsms.com - Year 2012, Vol 12, Issue 2
Abstract
In this paper, the four morphological operator’s erosion, dilation, opening and closing are used to detect the background. After the background is extracted, contrast of bad lightning image is improved by the application of operators based on Weber’s law notion Two contrast enhancement operators Block Analysis method and Opening by Reconstruction method are used. These operators avoid abrupt changes in intensity among different regions .In the final step, we enhance the image by using various filtering techniques. By applying filtering techniques, our image will be of good contrast and free from bad lightning.
