Structure Guided Salient Region Detector

This paper presents a novel method for detection of image interest regions called Structure Guided Salient Regions (SGSR). Following the information theoretic route to saliency detection, we extend Kadir et al.’s Salient Region detector by exploiting image structure information. The detected SGSRs are highly distinct and very selective. For planar scenes, their performance on repeatability tests under viewpoint changes is comparable to the state of the art. For 3D scenes, SGSRs are more likely to be repeatably detected under viewpoint change. Their usefulness for wide baseline matching is demonstrated with a real-world example, where their comparative advantages are shown.
