Face recognition method

Abstract

The invention discloses a face recognition method. The method comprises the following steps that: step 1, facial feature template data are collected and are arranged in a standard library, and at least one auxiliary library is set, and facial feature template data in the auxiliary libraries are added, updated, replaced, or deleted during a use process; step 2, facial feature template data to be matched are extracted from a photo to be matched or a face information electronic carrier to be matched, and are matched with the data in the standard library, face data matched with the data in the standard library are outputted normally; and if face data matched with the facial feature template data to be matched cannot be found in the standard library, the facial feature template data to be matched are further matched with the data in the auxiliary libraries, if face data matched with the facial feature template data to be matched exist in the auxiliary libraries, the face data are outputted.With the method adopted, the problem of excessively low recognition rate or recognition error of faces which are caused by shooting angles, age change, shielding objects can be solved, and a face recognition rate can be improved.

Description

technical field [0001] The invention relates to a face recognition method. Background technique [0002] Face recognition is a biometric technology for identity recognition based on human facial feature information, including a series of related technologies for building a face recognition system: face image acquisition, face positioning, face recognition preprocessing, identity confirmation and identity lookups, etc. In recent years, with the development of face recognition technology, more and more mature related products have appeared and are widely used in finance, government, factories, education, medical care, entertainment, Internet and many other fields and related departments. [0003] The main steps of the face technology that people are familiar with are: [0004] (1) Face image acquisition and detection [0005] Mainly collect face electronic information that meets the requirements through various hardware devices, including photos and video streams; then, det...
