Color Image Processing

Human vision is more sensitive to color than gray levels. Therefore, color image processing is important, although it requires more memory to store and longer execution times to process. There are different color models and each one is suitable for some application. In the RGB model, a color image is expressed in terms of the intensities of its red, green and blue components. In the HSI model, the intensity component is separated from the color components. This model can use the algorithms for gray level images. Some of the processing are based on those of gray level images and some are exclusive to color images.
