Matching 2.5D Scans for Face Recognition
Abstract. The performance of face recognition systems that use twodimensional images is dependent on consistent conditions such as lighting, pose, and facial appearance. We are dev...

Global Optimization for Alignment of Generalized Shapes
In this paper, we introduce a novel algorithm to solve global shape registration problems. We use gray-scale “images” to represent source shapes, and propose a novel twocompo...

Image-Set Based Face Recognition Using Boosted Global and Local Principal Angles
Face recognition using image-set or video sequence as input tends to be more robust since image-set or video sequence provides much more information than single snapshot about the ...

Spread spectrum-based watermarking for Tardos code-based fingerprinting for H.264/AVC video
In this paper, we present a novel approach for active fingerprinting of state of the art video codec H.264/AVC. Tardos probabilistic fingerprinting code is embedded in H.264/AVC v...

Hierarchical dictionary learning for invariant classification
Sparse representation theory has been increasingly used in the fields of signal processing and machine learning. The standard sparse models are not invariant to spatial transform...
