A Critical Low Light Image Enhancement Method: A Review

From last few years, there has been substantial work on image processing and wide improvements being carried out in image processing including resolutions and sensitivity. Despite these improvements, still there is a problem to capture a high dynamic range images and videos in low-light conditions especially when light is very low. If the intensity of noise is higher than the signal then the conventional de-noising techniques cannot work properly. For the said problem there are many approaches being developed for low-light image enhancement but still Low contrast and noise remains a barrier to visually pleasing videos in low light conditions. To capturing videos in concerts, parties, social gatherings, and in security monitoring situations are still an unanswered problem. In such conditions the image enhancement of low quality image is a really tedious job. This paper is elaborating a survey of different type of methods and technologies that have been used and implemented in the area of image enhancement. The study is further going on to find a technique so that more accuracy can obtained in image enhancement.
