Ultrasound images can be used to detect tumors that do not appear in the mammograms of
dense breasts. Several computer-aided diagnosis (CAD) systems based on this type of …

This paper develops a novel face recognition technique called Complete Gabor Fisher
Classifier (CGFC). Different from existing techniques that use Gabor filters for deriving the …

Researchers have recently found that the finger-knuckle-print (FKP), which refers to the
inherent skin patterns of the outer surface around the phalangeal joint of one's finger, has …

In this chapter, we address the problem of biometric identity recognition from the vasculature
of the human sclera. Specifically, we focus on the challenging task of multi-view sclera …

In this paper, a phase-based binarization model for ancient document images is proposed,
as well as a postprocessing method that can improve any binarization method and a ground …

Recently, as one of the most promising biometric traits, the vein has attracted the attention of
both academia and industry because of its living body identification and the convenience of …

The theory of phase congruency is that features such as step edges, roofs, and deltas
always reach the maximum phase of image harmonic components. We propose a modified …

In the field of biometric recognition, convenience and security of the system are highly
demanded. A large database usually leads to long response time and high computational …

The two key factors in a biometric identification system are its high identification rate and
convenience of device usage. In a finger-vein identification task, these two problems often …

Finger texture (FT) images acquired from different spectral lighting sensors reveal various
features. This inspires the idea of establishing a recognition model between FT features …
