A Review on Various contrast enhancement scheme for Dark Images
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 5
Abstract
Abstract : Contrast enhancement technique is used to enhance the perception of the image or scene. This enhancement controls the brightness difference between objects and their backgrounds. It also used as brightness preservation of image. Numerous contrast enhancement techniques are offered by various researchers for the betterment of the quality of images like contrast enhancement of HDR, DCT, DWT, Filtering etc. the common problem with image enhancement is difficult to achieve such images. Noise is an unwanted element of system that creates problem or interference. Contrast enhancement uses scaling to remove internal noise of dark images using DCT technique. Here in this paper we are presenting some techniques used for contrast enhancement of image.
