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 present disclosure relates to a person recognition method and device, and belongs to the technical field of person detection and recognition. The method includes: identifying the face features of the target person through the sample face features in the face database; Clothing features of sample characters in the database are acquired to identify the clothing features of the target person, obtain the second recognition confidence level with the highest matching degree of clothing, and then simultaneously identify the target person according to the first recognition confidence level and the second recognition confidence level. This disclosure improves the accuracy of character recognition by taking into account both facial features and clothing features when it is difficult to accurately identify a person's identity based on facial features, and at the same time satisfies the diversity of character recognition object samples, making character recognition The processing capacity is more flexible.

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...
