Dynamic threshold management method and system, electronic equipment and medium

Abstract

The invention provides a dynamic threshold management method and system, electronic equipment and a medium, and the method comprises: obtaining a comparison score distribution result through the similarity comparison of face images; and dynamically adjusting a comparison threshold value of the image processing equipment or each target object according to the comparison score distribution result. In order to overcome the influence of actual working conditions such as an application environment, application equipment and bottom library quality on a passing rate and a false identification rate, a comparison threshold value of image processing equipment or each target object is dynamically adjusted according to a distribution rule of a comparison score distribution result when the target object is a person or a non-person, and a relatively high passing rate and a relatively low false identification rate are ensured.

Description

[0001] This application is a divisional application for a patent application with an application date of July 16, 2020, an application number of 202010683491X, and an invention title of "A Dynamic Threshold Management Method, System, Equipment, and Medium". technical field [0002] The invention relates to image recognition technology, in particular to a dynamic threshold value management method, system, electronic equipment and media. Background technique [0003] In the face recognition process, the selection of the judgment threshold of face recognition is particularly critical. In the prior art, face recognition is performed by setting a static threshold, which may result in: the higher the threshold, the lower the pass rate and false recognition rate; The lower the threshold, the higher the pass rate and false positive rate. [0004] During the delivery process of face recognition equipment, due to the experience deviation of different delivery personnel and the complex...
