Abstract

The application discloses an image identification method, an image identification device, a metric learning method, a metric learning device, an image source identification method and an image source identification device. The image identification method comprises the following steps: getting a to-be-identified object image; extracting the object characteristics of the to-be-identified object image; selecting a similarity measurement model corresponding to the source category of the to-be-identified object image from a pre-trained measurement model set, and calculating the similarity between the object characteristics and registered image object characteristics as the basis of an output object identification result, wherein the measurement model set contains at least one similarity measurement model, and different similarity measurement models correspond to different source categories of object images. By using the method in image identification, the problem about asymmetric object image identification can be solved effectively, and higher robustness and higher accuracy are achieved for identification of to-be-identified object images of changeable sources.

Description

technical field [0001] This application relates to pattern recognition technology, in particular to an image recognition method and device. The present application also provides a metric learning method and device, and an image source identification method and device. Background technique [0002] Face recognition is one of the hot research topics in the fields of pattern recognition, image processing, machine vision, neural network and cognitive science in recent years. Face recognition usually refers to the computer technology that extracts discriminative visual features from face images and uses them to determine the identity of faces. It can be divided into two categories: face identification and face verification. Face identification refers to identifying the identity of a face image, that is, to determine which person's image a certain face image is; face verification refers to judging whether the identity of a face image is the claimed person. [0003] Existing face...
