In this paper the outline of complete vein patternrecognition system is introduced. An innovative method for finger vein image binarization is given in detail. the main purposes in the developed method are: lower time consuming comparing to other methods, simplicity and promising results achievement in spite of working with low contrast images. Boththe algorithm and the experimental results of the pattern extraction are presented in detail. the achieved results are compared with other binarization techniques to show the superiority of the worked out algorithm over the others. the algorithm has proved to be of less computational complexity and easier implementation.

Human-machine interaction requires the ability to analyze and discern human faces. Due to the nature of the 3D to 2D projection, the recognition of human faces from 2D images, in presence of pose and illumination variations, is intrinsically an ill-posed problem. the direct measurement of the shape for the face surface is now a feasible solution to overcome this problem and make it well-posed. this paper proposes a completely automatic algorithm for 3D face registration and matching based on the extraction of stable 3D facial features characterizing the face and the subsequent construction of a signature manifold. the facial features are extracted by performing a continuous-to-discrete scale-space analysis. Registration is driven from the matching of triplets of feature points and the registration error is computed as shape matching score. A major advantage of the proposed method is that no data pre-processing is required. Despite of the high dimensionality of the data (sets of 3D points, possibly withthe associate texture), the signature and hence the template generated is very small. therefore, the management of the biometric data associated to the user data, not only is very robust to environmental changes, but it is also very compact. the method has been tested against the Bosphorus 3D face database and the performances compared to the ICP baseline algorithm. Even in presence of noise in the data, the algorithm proved to be very robust and reported identification performances in line withthe current state of the art.

Iris texture is commonly thought to be highly discriminative between eyes and stable over individual lifetime, which makes iris particularly suitable for personal identification. However, iris texture also contains more information related to genes, which has been demonstrated by successful use of ethnic and gender classification based on iris. In this paper, we propose a novel ethnic classification method based on supervised codebook optimizing and Locality-constrained Linear Coding (LLC). the optimized codebook is composed of codes which are distinctive or mutual. Iris images from Asian and non-Asian are classified into two classes in experiments. Extensive experimental results show that the proposed method achieves encouraging classification rate and largely improves the ethnic classification performance comparing to existing algorithms.
