Embodiment Construction

[0016] Embodiments of the method for acquiring confidence in face recognition of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] figure 1 It is a flow chart of a method for acquiring confidence in face recognition in an embodiment. Such as figure 1 As shown, the face recognition confidence degree acquisition method of the present invention may comprise the following steps:

[0018] S1, obtaining the first face picture of the subject to be tested, and obtaining the second face picture in the preset face picture library; wherein, the face picture library is a database composed of multiple face pictures;

[0019] S2, calculating the similarity between the first human face picture and each second human face picture, and determining the maximum similarity;

[0020] S3. Calculate a confidence degree for identifying the object to be tested as a target object according to the maximum similarity; wherein the target object...

Abstract

The invention relates to a method and a system for acquiring confidence in face recognition. Wherein, the method includes: obtaining the first human face picture of the object to be tested, and obtaining the second human face picture in a preset human face picture library; wherein, the human face picture library is a database composed of a plurality of human face pictures ; Calculate the degree of similarity between the first human face picture and each second human face picture, and determine the maximum similarity; According to the maximum similarity calculation, the confidence that the object to be tested is identified as the target object is calculated; wherein, the The target object is an object to which the second face picture corresponding to the maximum similarity belongs. The method and system for obtaining confidence in face recognition can evaluate the effectiveness of face recognition results, improving the reliability of face recognition results.

Description

technical field [0001] The present invention relates to the technical field of face recognition, in particular to a method and system for acquiring confidence in face recognition. Background technique [0002] Face recognition is a technology that obtains a face image through a camera and analyzes it through a computer to identify the identity of the face image. Compared with other biometric technologies, face recognition technology has the advantages of convenient feature collection, no need for the target to put a finger on the fingerprint reader or align the retina with the iris scanner, and only need to collect the picture through the camera; Intrusive, this does not necessarily refer to taking pictures of the captured images without the knowledge of the person being captured. This resentment. Therefore, face recognition technology has a very broad development prospect, and has very important research value in the field of biometrics. [0003] The current face recogni...
