Salient Object Contour Detection Based on Boundary Similar Region

Abstract

Salient object contours are important cues for object detection and shape recognition in computer vision. We propose a novel contour detection method for salient object considering salient edges operator. The method traces continuous boundaries from salient edges, computes similar regions between boundaries with direction channel and distance by Boundary Similar Region (BSR) algorithm. Then we fill the boundary similar regions by linear interpolation method to ensure that boundaries belong to a same contour. We demonstrate our method applied to salient object segmentation. Experiments indicate that our method show better accuracy of salient object boundary. On the basis of edge manipulation, our method is compact and simple that performs efficiently.
