Abstract

A computing device for identifying a gesture performed by a tracked object in an image stream, said computing device comprising a memory and a controller, wherein said controller is configured to: determine a movement vector for the tracked object, compare the movement vector against a reference library of gestures, and thereby identify a gesturematching the movement vector, wherein said movement vector comprises at least one partial movement having a directionbeing identified by arelative angle and wherein said comparison is based on said relative angle. To be published with figure 23.

Description

technical field [0001] The present application relates to methods, computer-readable media, and computing devices for recognizing gestures made by objects, and more particularly to methods, computer-readable media, and computing devices for improving the recognition of gestures made by objects in video streams. The present application also relates to methods, computer-readable media, and computing devices for recognizing gestures made by a plurality of objects. technical background [0002] Developers have been trying to successfully implement vision-based control in contemporary devices such as game consoles, computers, and smartphones. Most attempts have been unsuccessful in providing control systems that are sufficiently efficient to actually operate in all real-life scenarios. Some examples of such systems are given below. [0003] US Patent Application Publication No. US2011299737 discloses a vision-based hand motion recognition system and method thereof. In one embo...
