1. A computing system, comprising: a storage to store shape definition information; and a processor to: determine contours of a silhouette of an object representation above a contour degree threshold, wherein a contour degree is determined based on the area of the contour with respect to itself; and identify a shape type of the object based on a comparison of the determined contours to the image shape definition information, wherein the processor is further to determine silhouette information of an inner portion of the object representation based on a second contour degree threshold.
