Palm print identifying method and palm print identifying device

Abstract

The invention relates to palm print identifying technology, and provides a palm print identifying method and a palm print identifying device aiming at the defects that the preprocessing requirement for the acquired palm print images is high in the prior palm print identifying technology, and the like. The palm print identifying method comprises the step of extracting the palm print characteristics of an image to be extracted, and the extraction specifically comprises the following steps: rotating and correcting the image to be extracted to generate a corrected image; carrying out convolution operation for the corrected image according to the preset Gabor wavelet, carrying out the operation of taking an amplitude value or a phase from the corrected image after the convolution operation, and generating a response image; and carrying out local binary mode characteristic extraction for the response image to acquire a local binary mode code of the image to be extracted so as to generate the palm print characteristics. The invention also provides the palm print identifying device. The technical proposal of the invention can provide rotational invariance and has high processing speed, so the technical proposal can achieve real-time palm print identification.

Description

technical field [0001] The invention relates to palmprint recognition technology, more specifically, to a palmprint recognition method and a palmprint recognition device. Background technique [0002] Identification methods are widely used in every aspect of people's daily lives. Traditional identification methods mainly include two types, the first is knowledge-based identification method, and the second is item-based identification method. Knowledge-based identification methods include identification methods based on authentication methods such as but not limited to passwords and passwords. The main defect of this method is that authentication methods such as passwords and passwords are easily forgotten. Item-based identification methods include identification methods based on authentication means such as but not limited to keys, ID cards, and smart cards. The main defect of this method is that authentication means such as keys, ID cards, and smart cards are easily lost. ...
