Description: In the field of biometrics, palmprint is a novel but promising technology. Limited work has been reported on palmprint identification and verification, despite the importance of palmprint features. There are many unique features in a palmprint image that can be used for personal identification. Principal lines, wrinkles, ridges, minutiae points, singular points, and texture are regarded as useful features for palmprint representation.

Description: This paper presents a novel segmentation algorithm for metallographic images, especially those objects without regular boundaries and homogeneous intensity. In metallographic quantification, the complex microstructures make the conventional approaches hard to achieve a satisfactory partition. We formulate the segmentation procedure as a new framework of iterative watershed region growing constrained by the ridge information. The seeds are selected by an effective double-threshold approach, and the ridges are superimposed as the highest waterlines in watershed transform. To tackle the over-segmentation problem, the blobs are merged iteratively with the utilization of Bayes classification rule. Experimental results show that the algorithm is effective in performing segmentation without too much parameter tuning.

Description: A fingerprint recognizing system is built with two
principal components: the fingerprint administrator and
the fingerprint recognizer. Fingerprints are identified by
their special features such as ridge endings, ridge
bifurcation, short ridges, and ridge enclosures, which are
collectively called the minutiae.

Description: 采用各向异性方法 填补一个缺损的轮廓，从而可以得到一个光滑完整的轮廓。- Completed contours correspond to ridges of an extension (ext) of the characteristic function of the uncompleted curve.
Anisotropic extension is performed on the characteristic function fbound of an image set given by
the binary map boundary to the whole image domain. Extension is initially driven by
\xi=(EigVect{1}, EigVect{2}) (which should match with the contour tangent direction)
computed as the direction of maximum coherence of the distance map to the contour to close.
It is updated every N iterations with DCV over the distance map to the ridges/thinning of the
evolved image.
Two different stop criteria are supported:
Number of Connected Components ( numcomp ). Contour Completion. Stop when the extended
contour (curve of level 1) has exactly Ncomp connected components.
Difference between two consecutive iterations ( tol )
Speed Stabilizes ( speed_stab ).
[extended]=ContourCompletion(BoundCond,f,DCVParam,StopParam,SaveParam)

Description: Image Edge Enhancing Coherence Filter Toolbox，各向异性非线性扩散滤波器-This toolbox will perform Anisotropic Non-Linear Diffusion filtering on a 2D gray/color or 3D image. This filtering will reduce the image noise while preserving the region edges, and also enhancing the edges by smoothing along them.
This is one of the more advanced image enhancement methods available, and also contains HDCS from october 2009. The result looks like an artist painted the image, with clear brush strokes along the image edges and ridges, see screen-shot.

Description: program for fingerprint recognition using minutia
The general shape of the fingerprint is generally used to pre-process the
images, and reduce the search in large s. This uses the general
directions of the lines of the fingerprint, and the presence of the core
and the delta. Several categories have been defined in the Henry system:
whorl, right loop, left loop, arch, and tented arch.
Most algorithms are using minutiae, the specific points like ridges
ending, bifurcation... Only the position and direction of these features
are stored in the signature for further comparison.-program for fingerprint recognition using minutia
