Wet and Wrinkled Fingerprint Recognition

When fingers wrinkle in water, they become harder to recognize as similar to a dry finger, based on fingerprint scans. Vision lab has taken this problem forward by introducing the WWF(Wet and Wrinkled Finger) dataset and baseline performances on a NBIS matcher and a commercial algorithm. We have also proposed a classifier to distinguish wrinkled from non-wrinkled by using Wavelet features.
