Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] The average feature-based target retrieval method provided by the first embodiment of the present invention can be applied to such as figure 1 In the shown application environment, the client (computer device) communicates with the server through the network. The server extracts the target image from multiple images of the same target input by the client, processes the target image, obtains the first normalized feature of the target image in eac...

Abstract

The invention relates to the technical field of face matching, and provides a target retrieval method and device based on average features and related equipment thereof, and the target retrieval method comprises the steps of extracting a target image from a plurality of obtained images of the same target; processing the target image to obtain a first normalized feature of the target image in eachdimension; calculating a first average feature of the target image in each dimension through the first normalized feature; obtaining an average value of pre-stored features on the corresponding dimension from a database, and encoding the first average feature according to the obtained average value to obtain a feature code; and comparing the feature code of the target image in each dimension withthe feature codes of different users in the database in the corresponding dimension to calculate the similarity between the target and the different users in the database, and determining the user with the maximum similarity as the target user. According to the embodiment of the invention, the method can solve a problem that a conventional face dynamic recognition method is lower in recognition efficiency.

Description

technical field [0001] The present invention relates to the technical field of face matching, in particular to an average feature-based target retrieval method, device and related equipment. Background technique [0002] With the rapid development of computer vision technology and deep learning technology, more and more vision algorithm applications have been implemented, among which face algorithm is the most widely used. In the field of public security, such as subway stations, high-speed rail stations, airports, customs ports and other places, there are not only face scanning for identity verification (1:1 verification), but also blacklisting (fugitives, smugglers, pickpockets, etc.) Monitoring is called dynamic face recognition. [0003] At present, it is generally to select multiple images with high quality from the captured face images, and then compare the multiple images with the images in the base library to determine whether the average score exceeds the set thres...
