Expression adaptive face recognition system

Abstract

The invention discloses an adaptive face recognition system, and relates to the technical field of face recognition. The adaptive face recognition system comprises a terminal console and a front-end collector, wherein the front-end collector comprises a control unit; the control unit is electrically connected with a face collection module, a face detection module, a voice interaction module, a communication module, a camera and a storage device; the terminal console comprises a terminal control unit; the terminal control unit is electrically connected with a terminal communication module, a terminal storage module, a face feature extraction module, a feature training module and a feature matching module; the terminal storage module is internally provided with a first model library and a second model library; and the feature matching module is internally provided with a first feature matching unit and a second feature matching unit. The adaptive face recognition system realizes recognition for different facial expressions of the same individual through recognition of a second feature extraction unit, the second feature matching unit and a second feature training unit for the facialexpressions, and solves a problem of difficult recognition caused by the single and fixed facial expressions.

Description

technical field [0001] The invention belongs to the technical field of face recognition, in particular to an expression adaptive face recognition system. Background technique [0002] Face recognition is a popular computer technology research field. It belongs to biometric identification technology, which is to distinguish individual organisms by their biological characteristics (generally referring to people). The unique feature of biometrics is very beneficial to the distinction of individuals, so face recognition technology is becoming more and more popular. [0003] At present, the commonly used face recognition system is to distinguish the face by extracting the feature vector of the face so as to realize the distinction of the individual, but generally the face expression used in the face recognition system for face feature training is relatively single or Uniformly adopt one expression, if you wear a mask with the same facial features as others, the face recognition ...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of facial expression self-adaptive face recognition system, through the recognition of facial expressions by the second feature extraction unit, the second feature matching unit and the second feature training unit, the recognition of different facial expressions of the same individual is realized , which solves the problem of difficult recognition caused by a single fixed facial expression
