Face Liveness Detection Using Shearlet Based Feature Descriptors


FACE LIVENESS DETECTION AND RECOGNITION USING SHEARLET BASED FEATURE DESCRIPTORS_Yuming LI

We demonstrate the results of DoG and LBP for comparison purpose. This demo video is available at this link: https://www.youtube.com/watch?v=kUCC0hLSJaU. In addition, in order to show that the proposed method can be directly used in real situation, we completed a real-time implementation of our method and tested it using real data which also include print photo attack, mobile photo attack and video attack. In this demo, 21 frames are analyzed for each detection and the final result is the average score of these 21 frames.

Novel data clustering for microarrays and image segmentation


Spectral Clustering Eigenvalue Problem

We develop novel algorithms and software on parallel computers for data clustering of large datasets. We are interested in applying our approach, e.g., for analysis of large datasets of microarrays or tiling arrays in molecular biology and for segmentation of high resolution images.

Multiresolution Functional Connectivity Analysis Refines Functional Connectivity Networks in Individual Brains


Recent advances in functional connectivity (FC) analysis of functional magnetic resonance imaging (fMRI) data facilitate the characterization of the brain’s intrinsic functional networks (FC-fMRI). Because the fMRI signal does not provides a perfect representation of neuronal activity, the potential for FC-fMRI to identify functionally relevant networks critically depends upon separating overlapping signals from one another and from external noise. As a step in data preconditioning, researchers often band-pass filter fMRI signals to the range from 0.01 Hz to 0.1 Hz.
