When performing feature extraction on face images, if a single feature extraction model is used for feature extraction for all images, due to the limited feature extraction capability of a single model, it will be difficult to handle face retrieval in all scenes; and if all images Using multiple feature extraction models for feature extraction, because each image needs to pass through all models, resulting in high computational complexity

The invention provides a face retrieval method and device. The method can comprise the steps of obtaining a to-be-retrieved face image; obtaining structured features of the face image, the structuredfeatures including features used for representing face attributes, and the structured features corresponding to a plurality of preset feature dimensions; obtaining unstructured features in one-to-onecorrespondence with a plurality of preset feature dimensions in the face image according to the structured features, the unstructured features including vectors used for representing the face features; and at least according to the unstructured features, obtaining standard features corresponding to a plurality of preset feature dimensions, and the standard features include features of the unstructured features after neural network conversion. According to the invention, the structured model is firstly utilized to divide the face image into different feature dimensions, and then the plurality of unstructured feature extraction models are utilized to perform feature extraction, so that the method and the device are suitable for processing face retrieval of a complex scene, and the calculation complexity is reduced.
Description
technical field [0001] This application relates to the field of computer vision, in particular to a face retrieval method and device. Background technique [0002] With the development of science and technology, face retrieval is an emerging biometric technology that combines computer image processing knowledge and biostatistics knowledge. At present, face retrieval is widely used in identification, identity verification and other related scenarios (such as security monitoring and access control gates, etc.). [0003] In the face retrieval technology, usually given a face image to be retrieved, the face retrieval device compares it with multiple face images in the specified face database to find the most similar face image or multiple face images. However, the face retrieval device does not directly calculate the similarity between the face image to be retrieved and the face image in the face database, but represents all images as features, and uses these features to calcu...
