In this paper, a novel method to verify the infrared finger-vein patterns is proposed for biometric purposes. Firstly, we select parameters for Gabor filter with eight orientations to exploit finger-vein network, then we extract vein patterns by the fusion of two distinct orientation results. Secondly, we utilize SIFT features to offset the effect of images rotation and shift impact during finger-vein...
Directional content-preserving features are extracted instead of the global ones. It first detects the initial curvature feature points based on the scale interaction model using Gabor filters with various scales in different directions. Then, the iterative geometric method is proposed to exact the content-preserving feature points. Next, by the radon transform, the two-dimensional distributing is...
Immersive sound spaces which are synthesized using virtual reality techniques have recently been developed to realize highly realistic telecommunication interactions. In real world soundscapes the sounds we usually listen to include background or ??ambient?? sounds such as the sounds of the ventilation system in a room. However, current virtual auditory display systems generate point sound sources...
Enhancement of image quality is a key problem for automated fingerprint recognition systems, especially for minutiae-based analysis. In this paper, five enhancement algorithms, including three popular enhancement algorithms and two combined algorithms, were reviewed. The FVC2000 DB1 B was chosen as the testing database. An algorithm evaluating platform based on minutiae comparison was implemented...
