Document Type and Number:
WIPO Patent Application WO/2020/052330
Kind Code:
A1
Abstract:
An optical imaging processing method and a storage medium. The method comprises the following steps: acquiring an image comprising a biometric pattern; detecting a bright spot on the image; and homogenizing the bright spot and a neighboring region thereof. The technical solution can effectively employ lensless imaging information, and effectively removes noise, bright spots, and dark spots from a single image obtained in a lensless imaging system so as to acquire, from the single image, a fingerprint image tile meeting software processing requirements. The invention is used to resolve the issue of processing biometric images in the field of lensless optical imaging.
