Face snapshot picture archiving method and device

Abstract

The invention provides a face snapshot picture archiving method and device. The face snapshot picture archiving method comprises the steps of acquiring a snapshot batch face snapshot picture set; according to the picture similarity, filing each face snapshot picture in the batch face snapshot picture set to obtain at least one temporary file; for each temporary file, calculating the face feature similarity between the temporary reference picture in the temporary file and a pre-stored archiving reference picture of each archiving file in an archiving file library; if the face feature similaritybetween the temporary reference picture and the filing reference picture in the first filing file is greater than or equal to a preset filing similarity threshold, classifying the temporary file intothe first filing file; and if the face feature similarity between the temporary reference picture and the filing reference picture in any filing archive is smaller than the filing similarity threshold, newly establishing the filing archive in the filing archive library, and classifying the temporary archive into the newly established filing archive. Archiving efficiency can be improved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and device for archiving snapshots of human faces. Background technique [0002] With the rapid development of face recognition technology, the application scenarios of face recognition technology have been greatly expanded, especially in the field of security. Whether at home or abroad, the public safety department in the security field has built a security business system with face recognition as the core by deploying a large number of video surveillance terminals, which has played a vital role in ensuring the safety of the department. However, with the continuous operation of the security business system, the captured pictures continue to accumulate, accumulating billions or even tens of billions of face capture pictures, which are stored in the database and become "sleeping" data, making the data low application value. [0003] In order to enhance the applic...

Problems solved by technology

[0004] But the present face capture picture archiving method needs to carry out face feature comparison with each archived file in the existing face capture picture archive library for each face capture picture captured, to determine the captured picture. The archiving file to which the face capture picture belongs, so as to realize the archiving of the face capture picture, requires a lot of computing resources, resulting in a long time for archiving and low archiving efficiency
