Title:
METHOD FOR SEPARATING FINGERPRINT FROM FINGERPRINT OVERLAY IMAGE USING DEEP-LEARNING ALGORITHM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/131517
Kind Code:
A1
Abstract:
Disclosed are a method for separating a fingerprint from a fingerprint overlay image using a deep-learning algorithm, and a device therefor. The fingerprint separation device: obtains a fingerprint separation image by separating a detection target fingerprint from a fingerprint overlay image, in which at least two fingerprints are overlaid, through a first deep-learning network trained to separate the overlaid fingerprints; generates a replacement image in which a region of interest, in which the plurality of fingerprints are overlaid in the fingerprint overlay image, is replaced with a region, corresponding to the region of interest, in the fingerprint separation image; and separates the background and the detection target fingerprint in the replacement image through a second deep-learning network trained to separate the background and the fingerprint, and outputs the detection target fingerprint.
