Contrast Enhancement for Color Images Using Improved Adaptive Multi-Scale Retinex Algorithm Approach
Murtaza Saadique Basha
Abstract: In this paper, enhancement of the color images using improved adaptive multi-scale retinex algorithm is proposed. This proposed method is an improvement over the classic multi scale retinex algorithm. First, the image is divided into a set of tiles. Two values such as b and a are calculated. The first value represents the minimum intensity for each tile and the second represents the difference between the minimum intensity and maximum intensity for each tile. In the next step, the values of a and b are expanded using bilinear interpolation. Once the values have been expanded, there are still values for each pixel of the MSR image. These values are used to normalize the image. The proposed method enhances the image in an effective way without introducing the halo artifacts and graying. The proposed method is well suited to be implemented on the GPU and by doing so real time processing speeds are achieved.
