Abstract

We will provide psychophysical evidence that recognition of parts of object contours is a necessary component of object recognition. It seems to be obvious that the recognition of parts of object contours is performed by applying a partial shape similarity measure to the query contour part and to the known contour parts. The recognition is completed once a sufficiently similar contour part is found in the database of known contour parts. We will derive necessary requirements for any partial shape similarity measure based on this scenario. We will show that existing shape similarity measures do not satisfy these requirements, and propose a new partial shape similarity measure.
