Gabor feature-based face detection method

Abstract

The invention discloses a Gabor feature-based face detection method, which comprises the following steps: obtaining a color face image; carrying out graying on the color face image to obtain a gray face image, and processing the grey face image by a Gabor filter to obtain a Gabor feature image; carrying out dimensionality reduction on the Gabor feature image by a principal component analysis method to obtain low-dimensional image data; and carrying out type judging identification on the low-dimensional image data and low-dimensional sample image data by a neighboring identification method, and selecting an image with the minimal distance as a face detection result. According to the Gabor feature-based face detection method, the detection result is relatively accurate.

Description

technical field [0001] The invention relates to the technical field of face detection, in particular to a face detection method based on Gabor features. Background technique [0002] The problem of identification is a difficult problem that human beings often encounter in daily production and life, and in many cases it is an important prerequisite for ensuring production and life. Traditional identification methods are mainly based on identification items and identification knowledge, which can be regarded as "what the subject has" and "what the subject knows" respectively. The former mainly includes keys, certificates, cards, etc. People who hold these identification items can get identity authentication in public and private places; the latter mainly includes passwords, user names, prompt question answers, etc. Anyone who knows this information can The identity of the identified subject can be obtained in the same way. However, in the case of some high security requireme...

AI Technical Summary

Problems solved by technology

Identification items are easily forged, lost or damaged, and identification knowledge is easily forgotten or stolen. Traditional identification is increasingly unsuitable for the modern age of rapid development of science and technology.
