Abstract

The invention provides a face key point detection method and device, electronic equipment and a storage medium. The method comprises: obtaining a to-be-detected face image; and inputting the face image to be detected into a face key point detection model to obtain a key point detection result output by the face key point detection model, wherein the face key point detection model is obtained by training based on a sample face image, and a sample face UV image, a sample face mask image and real coordinates of sample key points corresponding to the sample face image, and the face key point detection model is used for performing spatial self-attention enhancement on face features of the to-be-detected face image based on a face UV image and a face mask image of the to-be-detected face image to obtain face enhancement features, and performing face key point detection based on the face enhancement features. According to the method and the device provided by the invention, the accuracy of face key point detection is improved.

Description

technical field [0001] The present invention relates to the technical field of computer vision, in particular to a human face key point detection method, device, electronic equipment and storage medium. Background technique [0002] Facial keypoint detection is an important task in the computer field, and its purpose is to locate a set of predefined keypoints to understand the structure of the human face. Face keypoint detection is used in many face analysis tasks, such as face recognition, expression recognition, age estimation, etc. [0003] In the prior art, the key points of the face are usually detected based on the key point coordinates or the heat map of the face. Not only is it easy to miss the detailed texture information of the face, but also it is impossible to learn the global facial features of the face, so that the key points of the face can be detected low accuracy. Contents of the invention [0004] The present invention provides a human face key point de...
