… orientation code (DOC) approach for palmprint recognition is proposed. First, the paper studies
the rationale of the palmprint orientation … for palmprint orientation feature representation. …

… for palmprint recognition so far. In this paper, we propose a new descriptor of palmprint
named histogram of oriented lines (HOL), which is a variant of histogram of oriented gradients (…

… Abstract—Orientation features are successfully used in coding- based palmprint recognition
… to represent the orientation feature of the palmprint. The neighboring direction indicator …

… are more precise than the single dominant orientation to represent the orientation feature of
these … a simple and effective double half-orientation based method for palmprint recognition. …

… the discriminant orientation features learning and discriminant scale feature learning. Finally,
we conduct matching by employing the angular and utilize four bits to represent features. …

… for 3-D palmprint recognition. After calculating … palmprint data, we extract both line and
orientation features from it. The two types of features are then fused at either score level or feature …

… orientation features of palmprint, including the principal orientation and corresponding
orientation … propose a local orientation binary pattern (LOBP) for palmprint recognition. Different …

… For our study, the minutiae and orientation field features are heavily correlated as the ridge
direction information is embedded into them simultaneously. To improve the system’s perfor…
