Abstract

The present invention discloses an image recognition method and apparatus. The method comprises the following steps that: analysis signals are obtained from the analysis image of a face image, and the amplitude values of the analysis signals carry information characterizing illumination in the face image; the amplitude values in the analysis signals are normalized; and image recognition is performed on a face image which is reconstructed based on the normalized amplitude values. With the image recognition method and apparatus of the invention adopted, the technical problem of relatively low recognition rate of face recognition can be solved.

Description

technical field

[0001] The present invention relates to the field of face recognition, in particular to an image recognition method and device. Background technique

[0002] Principal Component Analysis (PCA) is a relatively accurate face recognition algorithm. Through certain training, the principal components of face images are extracted, and an unsupervised learning method is performed to realize face recognition and face discrimination. .

[0003] The existing principal component analysis (PCA) face recognition method is greatly affected by illumination and has low robustness to brightness transformation. When the image illumination changes, the recognition rate will be relatively low.

[0004] For the above problems, no effective solution has been proposed yet. Contents of the invention

[0005] Embodiments of the present invention provide an image recognition method and device to at least solve the technical problem of relatively low recognition rate of face recog...
