In this paper, we propose a color image enhancement method that uses retinex with a robust envelope to improve the visual appearance of an image. The word "retinex" is h...

The geometric features of images, such as edges, are difficult to represent. When a redundant transform is used for their extraction, the compression challenge is even more dif...
