Problems solved by technology

In the process of dynamic gesture recognition, gesture detection needs to be performed on consecutive image frames. At this time, if the operator's hand shakes slightly unintentionally, the mapping of the hand in the image frame will shake accordingly, resulting in the recognition of dynamic gestures. There will be a slight jitter, which will affect the operator's operating experience and accuracy

Abstract

The embodiment of the invention discloses a gesture recognition method and device. The method comprises the steps that the coordinates of the central point of a gesture in an th frame image is obtained, the coordinates of the actual central point of the gesture in the th frame image is determined as the coordinates of the actual central point of the gesture in an <i-1>th frame image when thecentral point of the gesture in the th frame image is in a preset zone, wherein i is an integer greater than or equal to 2, and the preset zone is the zone taking the actual central point of the gesture in the <i-1>th frame image as the center; dynamic gesture recognition is conducted according to the coordinates of the actual points of the gestures in each frame image. According to the method, instant feedback of hands in image frames caused by unaware shaking of the hands can be avoided, so that constant changing of recognized dynamic gestures is ensured.

Description

technical field [0001] The invention relates to artificial intelligence technology, in particular to a gesture recognition method and device. Background technique [0002] The gesture recognition function has gradually become an emerging function of terminal equipment such as electronic picture frames and household appliances. In the process of dynamic gesture recognition, gesture detection needs to be performed on consecutive image frames. At this time, if the operator's hand shakes slightly unintentionally, the mapping of the hand in the image frame will shake accordingly, resulting in the recognition of dynamic gestures. There will be a slight jitter, which will affect the operator's operating experience and accuracy. Contents of the invention [0003] Embodiments of the present invention provide a gesture recognition method and device, which can avoid immediate feedback of the hand in the image frame caused by unintentional shaking of the hand, thereby ensuring the co...
