Embodiment Construction

[0050]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0051] Embodiments of the present invention provide a method for collecting face pictures, such as figure 1 As shown, specifically, the following steps may be included:

[0052] S101. Extract facial features from multiple videos, and record appearance information of each extracted facial feature in the multiple videos, where the appearance information indicates the video to which the facial feature belongs.

[0053] S102. Cluster the extracted face features to obtain multiple cluster sets.

[0054] S103, for each cluster set, based on the occurrence information of each face feature in the cluster set, generate the face feature distribution information of the cluster set, the face feature distribution information represents the face features in the cluster set belongs to the v...

Abstract

Embodiments of the present invention provide a method and device for collecting human face pictures, wherein the method includes: extracting facial features from multiple videos, and recording the appearance information of each extracted facial feature in the multiple videos, Clustering the extracted face features to obtain multiple cluster sets, for each cluster set, based on the appearance information of each face feature in the cluster set, generating the face feature distribution information of the cluster set, From the above-mentioned multiple clustering sets, select the clustering set whose face feature distribution information is closest to the character distribution information of the specified person in the above-mentioned multiple videos, as the target clustering set, and collect the The video frame picture to which each face feature belongs is used as the face picture of the specified person; the embodiment of the present invention solves the problem that it is difficult to identify the specified person due to the difficulty in collecting the required face pictures of the specified person, Improved recall for person recognition.

Description

technical field [0001] The invention relates to the technical field of multimedia recognition, in particular to a method, device and electronic equipment for collecting face pictures. Background technique [0002] Face recognition is a biometric technology for identity recognition based on human facial feature information, which has gradually emerged in various fields; there are two main ways of face recognition, one is online matching, and the specific implementation steps are: Collect the face pictures of the specified person, screen the representative standard image of the specified person, and judge whether the image to be recognized is a picture of the specified person based on the similarity between the image to be recognized and the standard image; the other is model recognition, The specific implementation steps are: collect the face pictures of the specified person, use the collected face pictures to train the created model, obtain an independent model that can reco...
