Abstract: With the development of computer vision, image salient region detection plays an important role in the field of image processing. In order to detect the salient region of natural image exactly, a method of saliency detection based on region contrast is proposed. The method first processes the input image using superpixel segmentation, then calculates the region contrast by features of color and spatial, then combined with the distance of average vectors of pixel features between image sub-region and its neighborhood and the center prior to generate high quality saliency map. Compared with the other saliency detection methods, the experimental results show that this method can detect the salient region more sufficient and better suppress the background.
