Abstract: Region color features are extracted from color image according to the different color information of the different component in Hue-Saturation-Intensity color model, combined with region segmentation algorithm. Region color features act as the threshold properties which are used in local threshold segmentation method. So a moving object segmentation method according to the image region color features is presented. Segmentation experiments show the effectivity and feasibility of the segmentation method. A region segmentation method, which integrates the subregion merged technique into the gradient algorithm, is presented. Subregion merged technique can prevent two separate regions from incorrect combination to some extent. The contrast experiments of segmentation show the region segmentation method is better than the region growing algorithm on segmenting the region whose gray scale is distributed roughly.
