We address the problem of robust face recognition, in which both training and test image data might be corrupted due to occlusion and disguise. From standard face recognition algorithms such as Eigenfaces to recently proposed sparse representation-based classification (SRC) methods, most prior works did not consider possible contamination of data during(More)
— We present a novel method for classifying and estimating the categories and poses of deformable objects, such as clothing, from a set of depth images. The framework presented here represents the recognition part of the entire pipeline of dexterous manipulation of deformable objects, which contains grasping, recognition, regrasping, placing flat, and(More)
The use of bag-of-features (BOF) models has been a popular technique for image classification and retrieval. In order to better represent and discriminate images from different classes, we advance BOF and explore the self-similarities of visual words for improved performance. The proposed <i>self-similarity hypercubes</i> (SSH) model, which observes the(More)
Depth-based gesture cameras provide a promising and novel way to interface with computers. Nevertheless, this type of interaction remains challenging due to the complexity of finger interactions and the under large viewpoint variations. Existing middleware such as Intel Perceptual Computing SDK (PCSDK) or SoftKinetic IISU can provide abundant hand tracking(More)
For the task of robust face recognition, we particularly focus on the scenario in which training and test image data are corrupted due to occlusion or disguise. Prior standard face recognition methods like Eigenfaces or state-of-the-art approaches such as sparse representation-based classification did not consider possible contamination of data during(More)
With the recent proliferation of high-fidelity head-mounted displays (HMDs), there is increasing demand for realistic 3D content that can be integrated into virtual reality environments. However, creating photorealistic models is not only difficult but also time consuming. A simpler alternative involves scanning objects in the real world and rendering their(More)
