Abstract
This paper addresses the problem of wide dynamic range scenes and presents a new method of compressing the dynamic range of wide dynamic range scenes. This method is based on the Multiscale Retinex Algorithm. The paper presents the performance of the Multiscale Retinex Algorithm on wide dynamic range pictures. Two modifications that enhance the results obtained with the original Multi Scale Retinex algorithm for wide dynamic range pictures are proposed. The first modification is obtained by the recombination of the resulting image with the original picture in a certain weight. The second modification is achieved by adjusting the histogram of the resulting picture. The modifications improve the results of the original Multi Scale Retinex Algorithm in a way that retains the global contrast of brightness and the natural impression of the resulting image. The paper explores the performance of this modified algorithm on different wide dynamic range scenes and points out its advantages over other dynamic range compression algorithms.
