Abstract

The invention discloses a face key point positioning method. The method comprises the steps of obtaining a to-be-recognized face image; performing face key point recognition on the face image to obtain an initial position of each face key point in the face image; taking each human face key point as a target human face key point, and extracting a small picture of a preset size containing the targethuman face key point from the human face image according to the initial position of the target human face key point; recognizing a target face key point in each small picture, and determining an accurate position of the target face key point in the small picture; and determining the accurate position of the target face key point in the face image according to the accurate position of the target face key point in the small picture and the position of the small picture in the face image. According to the face key point positioning method, the recognition speed is increased, and the recognitionaccuracy is improved. The invention also provides a face key point positioning device and a storage medium.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a face key point positioning method, device and storage medium. Background technique [0002] At present, there are many face key point algorithms, but most of them are either to improve performance and facilitate terminal deployment, or to use relatively large models for key point prediction in order to improve accuracy, resulting in slow model reasoning. That is to say, traditional face key point recognition is either slow in recognition speed or low in recognition accuracy. Therefore, it is necessary to propose a fast and accurate facial key point recognition method. Contents of the invention [0003] Based on this, it is necessary to propose a fast and accurate facial key point location method, device and storage medium for the above problems. [0004] A face key point positioning method, comprising: [0005] Obtain the face image to be recognized; [0006] Ca...
