Abstract
Systems and techniques for efficient free-space finger recognition are herein described. A surface in a depth image may be identified. One or more blobs in the depth image may be identified. The identified blobs may be analyzed to determine if a blob intersects with an edge of the depth image and classified as a potential hand if the blob does intersect with the edge or classified as an object otherwise.
