Although palmprint based authentication approaches have shown promising results recently, efforts are still required to achieve higher performance with low time complexity for their use in real-life high security applications. Based on these requirements, the concept of two level matching scheme using line matching in Hough space and Curve segment Hausdorff Distance (CsHD) are explored and developed...
In this paper, we propose a novel approach for palmprint matching. We retrieve line-patterns in a rotation and translation invariant manner that tackles broken line problem. The local structure of line pattern is extracted as a set of pairwise angle relationships, which are simple, invariant to translation and rotation, robust to end-point erosion and segment error, and sufficient for discrimination...
In this paper, we propose a novel approach to retrieve line-patterns from large databases in a rotation and translation invariant manner, at the same time, tackle broken line problem. Line segments are extracted from an image as primitives. Each local structure is represented by a set of pair-wise angle relationships, which are simple, invariant to translation and rotation, robust to end-point erosion,...
This work proposes a line-based Hough transform method, which extracts global features for coarse-level filtering in two-stage palmprint identification system. This is a novel approach to the application of the Hough transform for feature extraction of palmprint. A principal line detection mechanism in transformed space is also proposed based on a flooding process, which is motivated by rainfalling...
The Hough transform (HT) is a powerful technique for line detection. Its main advantage is that it is relatively unaffected by noise or gaps in lines. This work proposes a line-based Hough transform method, which extracts global features for coarse-level filtering in hierarchical palmprint identification system. The local information extracted from position and orientation of individual line is used...
Palmprint-based personal identification is regarded as an effective method for automatically recognizing a person's identity. It is well-known for several advantages such as stable line features, low-resolution imaging, low-cost capturing device, and user friendliness. This paper presents a new approach to identify palmprints using modified line-based Hausdorff distance. Line edge map (LEM) of palmprint...
