Palm print palm vein image layer fusion method based on wavelet transformation and Gabor filter

Abstract

The invention discloses a palm print palm vein image layer fusion method based on wavelet transformation and a Gabor filter. The method comprises the following steps: 1, acquiring palm print and palm vein images, and then respectively extracting regions of interest (ROI); 2, performing image layer fusion based on the wavelet transformation and Gabor filtering on input ROI images, i.e., performing the wavelet transformation on the palm print palm vein images after ROI extraction by use of a two-dimensional Mallat algorithm, enhancing textures of high-frequency subimages by use of the Gabor filter, and finally obtaining images after fusion by reconstructing the images by use of a two-dimensional Mallet rapid algorithm; 3, performing subspace-based feature extraction on the obtained fusion images; and 4, performing classification by use of a nearest neighbor classifier. The palm print palm vein image layer fusion method based on the wavelet transformation and the Gabor filter, provided by the invention has the advantages of quite high security and quite high recognition rate.

Description

technical field [0001] The invention relates to the field of contact biometric identification technology, in particular to a palmprint and palm vein fusion method. Background technique [0002] The universality and necessity of computers is the inevitable result of the development of today's information technology, which makes the whole society a combination of information and network. How to further strengthen the security of social informatization and network has become the top priority of urgent problems to be solved. , and identity authentication is a basic method used throughout the ages. There are two traditional methods of identity authentication, one is identity authentication based on markers (keys, certificates); the other is identity authentication based on knowledge (passwords, card numbers), but the defects of both are through "Identity authentication, and these extraneous things are easy to be forged or impersonated. To eliminate these hidden dangers, we must ...
