Abstract

The invention provides a posture recognizing method and system as well as a computer program product. The method comprises the following steps of: providing a plurality of posture templates, wherein each posture template defines a first posture characteristic and a specific posture corresponding to the first posture characteristic; acquiring a plurality of images and generating a composite background model according to the images; obtaining at least one object image with an object according to the composite background model, wherein the object is provided with a plurality of edges; counting an included angle formed by every two adjacent edges in the plurality of edges to obtain a second posture characteristic corresponding to the object image; comparing the second posture characteristic of the object image with the first posture characteristic of each posture template; and when the second posture characteristic is similar to the first posture characteristic, obtaining a specific posture corresponding to the first posture characteristic.

Description

technical field [0001] The present invention relates to a gesture recognition method and system, and in particular to a method and system capable of dynamically generating a composite background model and automatically removing background images from images to obtain object images and recognize corresponding poses. Background technique [0002] With the popularity of electronic devices, such as computers and image capture devices, more and more applications and technologies are being developed to make operating these devices more convenient. [0003] In some technologies, the user can control the computer through gestures. Generally speaking, gesture recognition technology can be divided into two categories. The first category is that the user needs to wear accessories such as marking points or gloves to assist gesture recognition, and the other is the freehand gesture recognition method that the user does not need to wear auxiliary accessories. . From the perspective of u...
