Abstract

The invention discloses an intelligent interactive type face key point labeling method. The method comprises the following steps of obtaining a face rectangular frame through the face detection algorithm, and extracting a set P of face key points from the face rectangular frame; if the set P of face key points does not meet the requirement, establishing a 3D face model M by utilizing the set P of face key points, and re-projecting face key points in the 3D face model M into a 2D image to obtain a new set P1 of face key points; according to an operation instruction returned by a user, re-editing inaccurate key points in the set P1 of face key points, and re-predicting a set P3 of face key points by utilizing the edited P2 of face key points and the 3D face model M; if the set P3 of face key points meets the requirement, directly outputting the set P3 of face key points; otherwise, repeating the above steps until the requirement is met according to the set P3 of face key points. The above method can greatly improve the labeling efficiency of face key points. When the method is applied to different environments and different types of human faces, accurate results can be obtained rapidly.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to an intelligent interactive face key point labeling method. Background technique [0002] Face recognition is a biometric information recognition technology based on the facial feature information of the face. It has a wide range of applications in e-commerce, security and other fields. This task is just a simple problem for the human eye, but the image in the computer's eyes is just a string of ordinary 01 strings, so using a computer to perform face recognition is an extremely complex, difficult and highly practical important problem. [0003] The task of face recognition is generally divided into four steps: [0004] 1. Perform face detection on the image, and cut out a picture containing only the face from the original image; [0005] 2. Perform key point detection on the face in the picture obtained in step 1, and obtain the key points of the face corresponding to ...
