Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be further described in detail below in conjunction with specific embodiments. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other arbitrarily.

[0044] The inventor of the present application proposes to construct a face index in a massive face database by means of clustering. When performing face retrieval, firstly compare the face to be retrieved with a limited number of indexes, and then use the index to obtain the required The face range of the secondary comparison, and then perform secondary matching in a small range, thereby improving the efficiency of face retrieval.

[0045] Based on the above ideas, this embodiment provides a complete retrieval device for fast matching in a large number of faces, such a...

Abstract

The invention discloses a face matching retrieval device and method, and relates to the fields of image processing, matching, retrieval and the like. The face matching retrieval device at least comprises an index comparison server and a secondary comparison server, wherein the index comparison server is used for comparing face features of a face image to be retrieved with face features in a pre-established index library to obtain corresponding indexes, and each index in the index library corresponds to one type of face features; and the secondary comparison server is used for retrieving the face features of the to-be-retrieved face image in all the face features stored in the corresponding areas in the pre-established face feature database according to the indexes obtained by the index comparison server, and obtaining a comparison result.

Description

technical field [0001] The invention relates to the fields of image processing, matching, retrieval and the like, in particular to a scheme for fast matching and retrieval in massive human face images. Background technique [0002] With the development of image processing and pattern recognition technology, the application of face recognition and comparison is becoming more and more extensive. Especially with the development of video big data, it is often necessary to input a face image in the public security field, and then find a matching face in a massive face database. Face databases in the public security field often contain millions or even tens of millions of face images. How to quickly and accurately perform face matching and retrieval from a massive face database has become an urgent problem to be solved. [0003] At present, the method for fast matching of massive faces generally adopts parallel processing methods such as distributed. By adding machines, the mass...
