Color image enhancement is becoming an increasingly important research area. This paper reviews some image enhancement techniques developed specifically for gray-images and presents an extension and application to color images of a method that involves the decomposition of an image into background and texture components. A new image can be produced by applying multiplicative weights to the different components to bring out the texture. Desired color shifts can also be achieved by experimenting with the weights.
