Embodiment Construction

[0051] see figure 1 , which is a block diagram of the image-based gesture recognition system of the present invention. In the figure, the gesture recognition system includes a storage unit 11 , an image capture unit 12 , a first processing unit 13 , a comparison unit 14 and a second processing unit 15 . The storage unit 11 , such as a memory or a hard disk, stores a default start gesture 111 and a default end gesture 112 . The image capture unit 12 captures a plurality of image frames 121 . The image capture unit 12 is preferably a video camera, which can output continuous image frames. The first processing unit 13 performs a gesture detection 131 according to the plurality of image frames 121 to obtain a first gesture 132 . The comparison unit 14 judges whether the first gesture 132 matches the preset start gesture 111 .

[0052] If the comparison unit 14 judges that the first gesture 132 matches the preset start gesture 111 , the second processing unit 15 performs a move...

Abstract

The invention discloses a motion gesture recognition method and a motion gesture recognition system based on an image. The method comprises the following steps of: receiving a plurality of image pictures; executing gesture detection according to the plurality of image pictures to obtain a first gesture; if the first gesture accords with a predetermined starting gesture, executing mobile tracking according to hand positions in the plurality of image pictures to obtain a mobile gesture; in the process of executing the mobile tracking, executing the gesture detection according to the plurality of image pictures to obtain a second gesture; and if the second gesture accords with a predetermined ending gesture, stopping the mobile tracking.

Description

technical field [0001] The present invention relates to a hand detection system, in particular to an image-based gesture recognition method and system thereof that do not require a sensor to be arranged on a user's hand. Background technique [0002] For the fast-growing entertainment system, especially the game system, how to make the interactive interface between the user and the computer more friendly is an increasingly important issue. Among them, executing instructions through computer analysis of user actions has become the most likely interaction method in the future. However, the traditional solution often needs to configure a sensor on the user's finger. Although this can increase the accuracy of hand detection, it also increases the burden on the user. Another preferred method is to directly regard the user's hand as a device for issuing instructions, and analyze the movement of the user's hand by means of image processing to input instructions and control the com...
