New Finger Biometric Method Using Near Infrared Imaging

Abstract: In this paper, we propose a new finger biometric method. Infrared finger images are first captured, and then feature extraction is performed using a modified Gaussian high-pass filter through binarization, local binary pattern (LBP), and local derivative pattern (LDP) methods. Infrared finger images include the multimodal features of finger veins and finger geometries. Instead of extracting each feature using different methods, the modified Gaussian high-pass filter is fully convolved. Therefore, the extracted… Show more

“…A mapping table was created based on the mean and standard deviation of bins, over descriptors from 10 persons. A CIR of 86% is obtained with a descriptor of length 42 extracted by the LBP (16,7) over a sub-image (the image is divided into 16 square sub-images).…”

“…In ROI-based methods [16][17][18][19], the features are extracted from the whole ROI without finger vein network segmentation. Although promising experimental results are reported in [16][17][18][19]; in practice, these ROI-based methods may suffer from some limitations.…”
