Abstract

The invention discloses an image processing method and an image processing device. The image processing method is characterized in that an original biological characteristic image can be acquired, and a to-be-corrected area can be determined in the original biological characteristic image; according to a preset area template, the to-be-corrected area can be corrected based on the multi-characteristic point matching algorithm; the to-be-corrected area comprises the to-be-corrected palm print area, and the area template comprises the palm print area template. By adopting the above mentioned method, the spatial attitude of the palm print in the to-be-corrected palm print area after the correction is consistent with the spatial attitude of the palm print in the palm print area template, and therefore the to-be-corrected palm print area after the correction can be used for the subsequent matching authorization, and the reliability is high.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an image processing method and device. Background technique [0002] At present, biometric technology is widely used in the security field and is one of the main means of authenticating user identities. Biometric technology can be divided into physiological feature recognition technology and behavioral feature recognition technology according to the classification of characteristics. Palmprint recognition technology is a kind of physiological feature recognition technology. [0003] The physiological feature of the palm print can be collected conveniently by using a camera of a terminal (such as a mobile phone). Generally, when performing palmprint recognition based on a terminal, an image of the user's palm can be taken, and then a fixed area in the image is intercepted to determine the palmprint area, and then the palmprint area is combined with each palmprint stor...
