Abstract

The invention provides a binary image processing method for identity authentication. The method comprises steps: a palm vein image after binary processing is acquired, and the acquired binary image is refined; and image features after refinement are extracted, and a palm vein binary image is recognized. According to the binary image processing method for identity authentication, as for a palm vein acquisition image with low quality, the recognition range, the recognition speed and the precision are effectively improved.

Description

technical field [0001] The invention relates to image recognition, in particular to a binary image processing method for identity authentication. Background technique [0002] With the development of biometric authentication technology, face and fingerprint recognition can no longer meet the growing security requirements. In recent years, identification based on palm vein features has received extensive attention in the field of biometric identification. The palm vein image is easy to acquire and takes up little storage space, so its research has important application value. Authentication products related to palm vein recognition will surely play an important role in network security authentication. The existing palm vein recognition system can only process samples under good conditions, but for palmprint samples with dark images and low definition, the recognition rate is reduced. Large, making the recognition process difficult to achieve real-time. Contents of the in...
