Face detection and recognition method and device based on face key point correction

Abstract

The invention discloses a face detection and recognition method based on face key point correction. The method comprises a face detection and recognition model training method and a face detection andrecognition model using method. According to the face detection recognition model training method, a training data set is sent to a two-stage convolutional neural network for training, the first stage is a detection correction network, and detection part model training is completed; And the second level is an identification network to obtain an identification part model. The invention discloses aface detection recognition model using method. and inputting an image to be detected into the trained detection correction network to obtain a human face key point position coordinate, cutting and correcting the image to be detected according to the human face key point position, and inputting the corrected image into the trained recognition network to obtain human face identity recognition information.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a face detection and recognition method and device based on face key point correction. Background technique [0002] With the development of deep learning technology and the rapid improvement of computer computing power, the fields of artificial intelligence, computer vision and image processing are developing rapidly. Among them, face recognition, as a classic topic in the field of computer vision, has great research and application value, and has a high demand for it. The main problem solved by face recognition is that for an input image containing a human face, the algorithm can automatically extract the facial features on the image, and recognize the facial image according to the features, and give the recognition result. [0003] At present, face recognition related technologies have made great progress, and some successful applications have appeared. Traditional face recogn...
