On principal lines and principal points

Palmprint verification based on principal lines

In this paper, we propose a novel palmprint verification approach based on principal lines. In feature extraction stage, the modified finite Radon transform is proposed, which can extract principal lines effectively and efficiently even in the case that the palmprint images contain many long and strong wrinkles. In matching stage, a matching algorithm based on pixel-to-area comparison is devise...

Methods for Estimating Principal Points

Palmprint classification using principal lines

This paper proposes a novel algorithm for the automatic classification of low-resolution palmprints. First we use some directional line detectors to extract the principal lines according to their characteristics and their definitions in two steps: the potential beginnings (“line initials”) of the principal lines are extracted and then, on the basis of these line initials, a recursive process is...

On the Patterns of Principal Curvature Lines around a Curve of Umbilic Points

In this paper is studied the behavior of principal curvature lines near a curve of umbilic points of a smooth surface.
