Image Enhancement Based on Color Histogram and DCT Approach

This paper presents a new approach for color enhancement of the images that is based on the compressed domain techniqueand histogram equalization. My proposed technique is simple but more effective than some of old existing techniques like AR,MSE and SF-CES. We use the treatment of the chromatic components, while previous techniques treated only the luminance component. Also it is computationally more efficient than the spatial domain based method, so it is provide better color enhancement compressed domain based approaches.
