Embodiment Construction

[0023] A kind of camouflaged face hierarchical recognition method, such as figure 1 As shown in the logic block diagram of the camouflaged face layered recognition algorithm, two-layer classifiers are used to perform layered recognition on the face of the recognition object. The second layer classifier is an individual face feature recognition classifier for identifying the identity of the object, and the second layer classifier further includes a traditional face recognition classifier for a non-disguised face and a fake person for a disguised face. Face recognition classifier, described method comprises the following steps:

[0024] 1. Collect the face image feature data of the identified object through the visible light sensor;

[0025] 2. Carry out general camouflage feature recognition in the first layer classifier, compare the feature data of the face image collected by the visible light sensor with the general feature data of the camouflage face in the database, judge ...

Abstract

The invention provides a face recognition technology, which comprises two layers of classifiers. The technology comprises the following steps: establishing a first-layer classifier which can recognize disguise by studying a plurality of disguise face samples; recognizing undisguised faces and disguised faces by two classifiers at the second layer respectively; in combination with a visible light sensor and an infrared sensor, acquiring a face visible light image and an infrared image of a recognition object respectively; and transmitting the visible light image and an infrared image to a computer for layered recognition so as to determine whether the object is one in a database or not in the database. Through the technology, the problem that the disguised face cannot be recognized or the recognition rate is low by the traditional face recognition technology is effectively solved, and the technology has a wide application prospect.

Description

technical field [0001] The invention relates to a biometric feature recognition technology, in particular to a method and system for layered recognition of disguised human faces. Background technique [0002] Face recognition is to judge whether the object is the same person as the person recorded in the database according to the face image characteristics of the recognition object. It has broad application prospects due to its advantages, such as identifying recorded terrorists or criminals in airports. However, the recognition object usually camouflages the face to cover the original features of some areas of the face, which puts high demands on the face recognition system. A fake face usually refers to a face that has been altered intentionally or unintentionally, such as wearing glasses or having a beard, makeup, excessively long hair that covers part of the face, or a scarf that covers part of the face. The existing face recognition system is very inefficient for this...
