Embodiment Construction

[0047] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0048] figure 1 It is a flow chart of a person recognition method according to an exemplary embodiment, and this embodiment is described by taking the person recognition method to be configured in a person recognition device as an example. The person recognition method may include the following steps:

[0049] In step 101, facial features of a target person in an input picture are ac...

Abstract

The invention relates to a person identification method and a person identification device, and belongs to the technical field of person detection and identification. The method comprises the steps of identifying face features of a target person based on sample face features in a face database, identifying clothes features of the target person according to sample person clothes features in a clothes database if judging that a first identification confidence with the highest degree of face matching is smaller than a preset first threshold, acquiring a second identification confidence with the highest degree of clothes matching, and identifying the target person according to the first identification confidence and the second identification confidence. According to the invention, when the identity of a person is hard to identity accurately based on the face features, the identity of the person is identified based on both the face features and the clothes features. Therefore, the accuracy of person identification is improved, the diversity of person identification object samples is satisfied, and person identification can be handled more flexibly.

Description

technical field [0001] The present disclosure relates to the technical field of person detection and recognition, and in particular to a method and device for person recognition. Background technique [0002] Technology promotes the rapid increase of multimedia data, and the understanding of pictures and videos is becoming more and more important. Among them, character recognition is particularly critical. Therefore, a large number of face detection and recognition algorithms have emerged as the times require. [0003] In related technologies, face recognition means that the system uses the face to confirm or search the identity of a person. The face recognition technology is based on the facial features of a person. For the input face image or video stream, it is first judged whether there is a person or not. If there is a human face, the position, size and position information of each main facial organ are further given, and based on these information, the identity feature...
