The relative topological relationship among minutiae was used in fingerprint matching for its changeless characteristics in distorted fingerprints. Each minutia was defined by a characteristic record in which the minutia type and the relative topological relationship among the minutia and its 5 nearest neighbors are included. The fingerprints matched or not(More)
This paper presents a novel monitor which uses ARM controller AT91SAM7S64 as its main processor, LCM (Liquid Crystal Display Module) for displaying ECG waves, SD (Secure Digital memory) card for data storage and RF module PTR8000 for radio data transmission. This portable monitor boasts alarm function for abnormality and can provide dynamic ECG monitoring(More)
Attributions including the type of minutiae, the curvature of ridge, the length ratio of 2 line segments of ridge and the relative topological relationship among minutiae and ridges were used in partial and/or nonlinear distorted fingerprint matching. Three kinds of criterions were defined to describe the pattern of fingerprint. Fingerprint was matched in(More)
