Vein image recognition method and device, electronic equipment and readable storage medium

Abstract

The invention provides a vein image recognition method and device, electronic equipment and a readable storage medium, and relates to the technical field of image processing. According to the method, ROI extraction is carried out on an original vein image to obtain an ROI image containing a vein region, so that some useless regions can be removed, subsequent useless feature extraction can be reduced, vein features can be effectively extracted; and then phase-consistent edge detection and feature extraction are carried out on the ROI image. Therefore, the target image containing the phase consistency characteristics in different directions can be obtained, and the extracted phase consistency characteristics are less influenced by the image brightness and contrast, so that the vein characteristics can be better extracted, the target image can be matched with the preset template image, and the original vein image can be identified more accurately.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular, to a vein image recognition method, device, electronic equipment and readable storage medium. Background technique [0002] Vein recognition (such as finger veins, dorsal veins, palm veins, etc.) technology, as a biometric identification technology, has received extensive attention at present, and it has the advantages of uniqueness, anti-counterfeiting, living body measurement and user-friendliness. However, limited by the imaging quality environment, the collected vein images usually have problems such as low contrast, blur, and noise interference, resulting in poor image quality. Therefore, how to extract more efficient and robust vein feature information from such low-quality vein images is one of the key technologies for developing a vein authentication system. [0003] The existing method is generally to extract the features of the entire vein image, and g...
