Local descriptors have been wildly explored and utilized in image retrieval because of their transformation invariance. In this paper, we propose an improved set of features extarcted from local descriptors for more effective and efficient image retrieval. We propose a salient region selection method to detect human’s Region Of Interest (hROI) from an image, which incorporates the Canny edge algorithm and the convex hull method into Itti’s saliency model for obtaining hROI’s. Our approach is a… CONTINUE READING
