Most existing biometric systems are fragile to spoofing attacks with fake biometric data. We seek for effective appearance features to distinguish fake from real biometric data via image analysis and machine learning methods.

Robust fingerprint image processing is critical to reliable and accurate automated fingerprint recognition. We apply statistical and deep learning methods to model fingerprint featrues and pre-process fingerprint images.

Modern crowd counting methods usually employ deep neural networks (DNN) to estimate crowd counts via density regression. Despite their significant improvements, the regression-based methods are incapable of providing the detection of individuals in crowds. The detection-based methods, on the other hand, have not been largely explored in recent trends of crowd counting due to the needs for expensive bounding box annotations. In this work, we instead propose a new deep detection network with only point supervision required. It can simultaneously detect the size and ...

Face alignment and 3D face reconstruction are traditionally accomplished as separated tasks. By exploring the strong correlation between 2D landmarks and 3D shapes, in contrast, we propose a joint face alignment and 3D face reconstruction method to simultaneously solve these two problems for 2D face images of arbitrary poses and expressions. This method, based on a summation model of 3D faces and cascaded regression in 2D and 3D shape spaces, ...

Three-dimensional (3D) faces are increasingly utilized in many face-related tasks. Despite the promising improvement achieved by 3D face technology, it is still hard to thoroughly evaluate the performance and effect of 3D face technology in real-world applications where variations frequently occur in pose, illumination, expression and many other factors. This is due to the lack of benchmark databases that contain both high precision full-view 3D faces and their 2D face images/videos under different conditions. In this paper, we present such a multi-dimensional face database (namely Multi-Dim) of ...
