Color Image Segmentation Based on HIS Model

In this paper, a new approach to automatic color image segmentation based on HIS model is presented. First, color image is transformed from RGB model to HIS model, in which image data is separated into chromaticity and brightness. Second, chromaticity is segmented by an algorithm based on J-image ,while brightness is segmented by watershed algorithm, then their results are combined as a final result. Experiments show that the new approach can be implemented efficiently.
