A New Light Detection Algorithm for Low-Light Images from DMSP/OLS

So far, by means of the analysis of low-light image from DMSP/OLS, many products can be obtained. These products are used in many areas such as urban extents evaluation, population studies and night-time low cloud and fog detection. In this paper, a new light detection algorithm for low-light images from DMSP/OLS is proposed. And compared with the Elvidge´s algorithm, the advantages of this proposed algorithm are analyzed. The experiment results show that the proposed algorithm can be used in the light detection of low-light images and show great advantages than Elvidge´s algorithm.
