Abstract :
SIFT features have known limitations for matching features under changes in 3D pose of the object. We investigate the use of multimodal information from the range and intensity domains as an approach to mitigating the effects of changes in view point. In this investigation we outline an experimental procedure applied to range and intensity images of real-world objects captured using a stereo camera pair and calibrated turntable setup offering reliable ground truth for the 3D motion of surface locations. From our investigation we propose a novel surface descriptor, EC-SIFT, which shows a significant improvement on state of the art performance in the experiments we present.
