英文摘要：

Saliency detection plays an important role in computer vision. In order to solve the problems of edge loss and over segmenta- tion in context-aware C CA ） algorithm, a new saliency detection algorithm combining manifold ranking and energy equation, called MREESD is proposed. The algorithm uses the superpixel segmentation method to divide the image into blocks, puts a new method for calculating the weights of superpixels and selecting saliency seeds. After combining a new way-manifold ranking computing the sali- ency map, using the energy equation to adjust the saliency map, also using the threshold segmentation for the obtained saliency map, fi- nally the foreground and background of the original image are separated by adding the binary map to the original image. The proposed algorithm has been tested on MSRA1000 image saliency detection database. The precision-recall curve shows that a higher precision and F-measure can be obtained than other methods. The experimental result shows that the proposed algorithm effectively solves the edge loss and over segmentation and it＇s more accurate in segmentation.
