Abstract

The invention provides a face key point detection method and device, electronic equipment and a storage medium, and is used for improving the problem that the accuracy of key point detection on a faceimage is relatively low. The method comprises the following steps: obtaining a plurality of face images and image annotation of each face image, wherein the image annotation is a key point annotatedfor the contour shape of a sensory organ in the face image; generating mask labels according to the key points in each image label, obtaining a plurality of mask labels, and the mask labels representing the probability that the key points in the face image are shielded; and taking the plurality of face images as training data, taking the plurality of mask labels and the image labels of the plurality of face images as training labels, and training the mask branches and the key point branches in the key point detection network to obtain a trained key point detection model, the key point detection model being used for detecting face key points in the images.

Description

technical field [0001] The present application relates to the technical fields of machine learning, computer vision and image recognition, and in particular, to a face key point detection method, device, electronic equipment and storage medium. Background technique [0002] Face key point detection is a technology that automatically searches for defined face feature points in any image. The key points of the face here are specific such as: pupils, nose, and corners of the mouth; face key point detection in computer vision Face key point detection is a key step in the field of face recognition and analysis. [0003] At present, when the quality of the face image is very good, using the current face key point detection algorithm to detect the face key points in the image to be detected can obtain ideal results. However, in the specific practice process, it is found that there are different degrees of occlusion in the collected images to be detected, especially in many scenes ...
