Although some developments have been achieved in finger vein recognition recently, the image deformation problem has received relatively less attention and still intractable. In this paper, the reason and the harmfulness of this problem are analyzed firstly. And then, a deformable finger vein recognition framework is proposed to deal with this problem, consisting of the improved vein PCA-SIFT feature...
State-of-the-art cost-sensitive learning based techniques in biometrics ignore cost difference between users and determine the loss only based on the misrecognition category. In practice, this may not always hold and the user individuality may also affect the loss of misrecognition. For example, misrecognizing an imposter as an administrator can cause a much more serious loss than misrecognizing it...
Finger vein is a new and promising trait in biometric recognition and some related progress have been achieved in recent years. Considering that there are many different sensors in a biometric system, sensor interoperability is a very important issue and still neglected in the state-of-the-art finger vein recognition. Based on the analysis of the shortcomings in the current finger vein ROI extraction...
Health was brilliantly defined in our traditional Chinese medicine masterpiece Huangdi Neijing more than two thousand years ago. For example, it deems the utility of body and soul, harmony between man and nature, equilibrium of Yin and Yang as the achievement of Yin Yang balance and good spirit. Meanwhile, Huangdi Neijing also creatively raised the preventive treatment of disease theory, a very good...
Dynamic Time Wrapping is a non-linear distance measure solution, widely used in query by humming. This paper have a body of work on cross-sentence retrieval, end point loose, cost function and their improvements to raise DTW performance of query by humming. Based on these researches we build a prototype of hierarchical matching humming system. During the test of database contains 500 songs and 55...
Facial expression recognition is one of the most popular topics in emotion analysis. Most facial expression recognition systems are implemented by general expression models. Since facial expressions may be expressed differently by different people, inaccurate results are unavoidable. The proposed facial expression recognition system recognizes facial expressions using facial features of the individual...
Aiming at intensive data processing in grid environment, a grid platform IDPGP is constructed based on Globus Toolkit 4, OGSA-DAI, Condor and PBS. This platform mainly provides grid information acquirement service, grid resource management service, data access and integration service, which can realize grid resources sharing, intensive data access and processing. In the grid resource management service,...
