FingerNet: An unified deep network for fingerprint minutiae extraction

Abstract: Minutiae extraction is of critical importance in automated fingerprint recognition.Previous works on rolled/slap fingerprints failed on latent fingerprints due to noisy ridge patterns and complex background noises. In this paper, we propose a new way to design deep convolutional network combining domain knowledge and the representation ability of deep learning. In terms of orientation estimation, segmentation, enhancement and minutiae extraction, several typical traditional methods performed well on rolled/sla… Show more

“…Unlike existing works using plain convolutional neural network [21,22] or sliding window [18,3] to process each patch with fixed size and stride, we use a deeper residual learning based network with more pooling layers to scale down the region patch. Specifically, we get the output after the 2 nd , 3 rd , and 4 th pooling layer to feed to an ASPP network [2] with corresponding rates for multiscale segmentation.…”

“…Using non-maximum suppression to reduce the number of candidates is common in object detection [7,17]. Some of the candidate regions are deleted to get a reliable minutiae score map by setting a hard threshold [3] or using heuristics [21,22]. However, a hard threshold can also suppress valid minutiae locations.…”

“…Convolutional neural networks (CNNs) [20] have brought unprecedented success in many computer vision tasks, including some recent works addressing fingerprint extraction and analysis [1,2]. On the other hand, fingerprint restoration and enhancement have been traditionally studied using classical example-based and regression methods [3,4,5,8] [6,10,11,17,18], the recent ECCV 2018 ChaLearn competition 3 has started to motivate researchers to develop deep learning algorithms that can restore fingerprint images that contain artifacts such as noise, scratches [7,9], etc.…”
