An approach for image segmentation based on visual saliency is proposed in this paper. First low-level visual features of the image are extracted. Local saliency, global saliency and rarity saliency are computed for each feature figure to get the feature conspicuity figures. Then these conspicuity figures are integrated to generate the saliency figure. The saliency figure is segmented using a threshold and a binary mask figure is obtained. Finally the foreground and background of the original image are separated by adding the binary figure to the original image. The proposed model has been tested on many natural images. Experimental results show that the proposed approach is valid and the segmentation results are consistent with human visual system.
