Abstract

The invention relates to a face key point detection method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining a to-be-detected face image which is a face image of a to-be-detected frame; According to the to-be-detected face image, determining a local image comprising each key point in the to-be-detected face image; Based on the local images, candidate points of the key points corresponding to the local images are determined respectively; And performing joint constraint on the candidate points of each key point to determine each face key point. Due to the fact that the overall face image to be detected comprises the local images of all the key points, the candidate points of the corresponding key points in the local images are determined. Thecalculation amount can be reduced, and the determination efficiency of key point candidate points is improved. Therefore, the detection efficiency of the key points of each face can be improved.

Description

technical field [0001] The present application relates to the field of artificial intelligence, in particular to a facial key point detection method, device, computer equipment and storage medium. Background technique [0002] Facial key point detection technology plays a vital role in applications such as face recognition, face registration, and facial makeup. The traditional face key point detection method is based on the global features of the face for face key point detection. For example, face key point detection (Landmark Detection) refers to positioning the position coordinates of key points in a face image. When performing face key point detection, such as figure 1 As shown in Fig. 1, the entire face image is used as input, and the position coordinates of all key points of the face are simultaneously output through the neural network or mathematical model. [0003] The traditional key point detection method uses the entire face image as the detection object to det...
