Abstract

The invention discloses a face key point positioning method and device, which belong to the technical field of image processing. The method includes: acquiring a face image containing a target face, determining a face frame of the target face in the face image; determining n faces in the target face according to the face frame and the first positioning algorithm The position of the key point; n≥3; from the candidate face, select a similar face whose position of the corresponding key point matches the position of n key points in the target face; determine the screened similar person according to the second positioning algorithm The positions of m key points in the face, where m is a positive integer; solves the problem that there will be a large deviation in the position of each key point obtained by the terminal in the prior art; it can improve the position of each key point obtained by positioning. effect on accuracy.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for locating key points of a human face. Background technique [0002] Face landmark location is an important technology in face image research. This technology directly affects various image processing technologies related to face recognition, such as face recognition, face attribute recognition (gender recognition, gesture recognition, and age recognition) and face beautification. [0003] Existing face key point localization methods usually include: determine the face frame of the face by the face detector, locate the face according to the ESR (Explicit Shape Regressor, display shape regression) positioning algorithm and the face frame, and obtain the face frame. Keypoints in the face. [0004] In the process of realizing the present invention, the inventors found that the prior art has at least the following problems: the positioning method is h...
