Abstract

Images taken under low light conditions or at night time has significantly less details compared to images taken under proper lighting. For computer vision applications, this kind of image is not acceptable as loss of visibility might result in undesirable output. It is also not very convenient for observation and for accurate analysis. To overcome this issue, different techniques have been used for low light images. In this paper, we presented a hybrid approach to enhance the visibility of the low light image by fusion of Robust Retinex Model (RRM) and Fusion based enhancement methods. The performances of existing and proposed system are compared based on the average entropy of input images. Different split ratio of multiplying factors have been tried to achieve the best results.

Keywords: Visibility enhancement , computer vision, Retinex method, fusion based methods.
