Title:
FAST HAND TRACKING METHOD, DEVICE, TERMINAL, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/200785
Kind Code:
A1
Abstract:
A fast hand tracking method comprises: displaying, on a display interface, a video containing a hand region acquired by an imaging apparatus; receiving a bounding box marked by a user on the video containing the hand region; extracting a histogram-of-oriented-gradient (HOG) feature of a region marked by the bounding box, and segmenting, according to the HOG feature, the region marked by the bounding box, so as to obtain a hand image; and tracking the hand image by means of a continuously adaptive mean shift operator. The present application further provides a fast hand tracking device, a terminal, and a storage medium. The present application enables fast extraction of a HOG feature in a bounding box marked by a user, and accurately performs segmentation to obtain a hand region according to the HOG feature, thereby achieving a better tracking result.
