Title:
LIP MOVEMENT DETECTION METHOD AND APPARATUS, STORAGE MEDIUM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/037280
Kind Code:
A1
Abstract:
The present application relates to the technical field of image processing, and specifically relates to a lip movement detection method, a lip movement detection apparatus, a computer-readable storage medium and an electronic device, which solve the problems of weak generalization ability and poor robustness of a traditional lip movement detection method. According to the lip movement detection method provided in an embodiment of the present application, a lip movement detection result of a target user is determined on the basis of a reference lip spacing of the target user in a current image frame, wherein the reference lip spacing is determined on the basis of a relative relationship between a lip spacing and a reference distance of the lip spacing, and the reference lip spacing is thus a relative value. When an image capture angle is changed, the lip spacing and the reference distance of the lip spacing are simultaneously reduced or increased. Therefore, the reference lip spacing determined on the basis of the relative relationship between the lip spacing and the reference distance of the lip spacing changes little or even not at all. That is, the reference lip spacing is not easily affected by factors such as the image capture angle and image capture distance, thus improving the robustness of the lip movement detection method.
