Method for binarizing and post-processing fingerprint image based on orientation information
|
Abstract:
Fingerprint image binarization,as an important part of fingerprint image preprocessing,is the precondition of fingerprint identification.In order to utilize the texture feature of the fingerprint images effectively,the orientation information was introduced into fingerprint image binarization.After considering the fingerprint image orientation information and adaptive local threshold synthetically,a complete set of adaptive local threshold binarization and post-processing algorithm was brought forward combi...
