Abstract

A face matching method, device and apparatus, and a computer readable storage medium are disclosed. The method includes: obtaining a target face region image of a target face image and at least two human face organ region images through a candidate region network model, and then obtaining at least two target face feature point and corresponding feature vector through the cascade convolution neuralnetwork model, combining the target face feature points to obtain feature combinations; according to the feature vector of the target face feature point in the feature combination and the feature retrieval database established in advance, performing iterative matching on the combinations one by one to obtain an image set matching all the feature combinations, and perofrming similarity calculationbetween the feature vector of the target face feature point and the image set to obtain a face matching result. The invention can reduce the search range, improve the search speed, and improve the user's use experience.

Description

technical field [0001] The present invention relates to the field of computer image processing, in particular to a face matching method, device, equipment and computer-readable storage medium. Background technique [0002] Face image matching is an important branch in the field of image matching. With the advent of the automated information age, face image matching has more and more applications in real life. Because face information is unique, difficult to forge and easy to collect, it is widely used in access control systems, video surveillance and identity verification technologies. [0003] The existing face image feature matching process is to extract the face image features in the database, search according to the similarity with the target face image features, and sort according to the similarity, so as to realize the process of face verification. The current face retrieval method is to locate the key points of the face, and then according to the geometric attribute...
