Existing methods on video-based action recognition are generally view-dependent, i.e., performing recognition from the same views seen in the training data. We present a novel multiview spatio-temporal and-or graph (MST-AOG) representation for cross-view action recognition, i.e., the recognition is performed on the video from an unknown and unseen view. As(More)
BACKGROUND More than 1 million tuberculosis (TB) patients are receiving the standard anti-TB treatment provided by China National Tuberculosis Prevention and Control Scheme (CNTS) in China every year. Adverse reactions (ADRs) induced by anti-TB drugs could both do harm to patients and lead to anti-TB treatment failure. The ADACS aimed to explore ADRs'(More)
The purpose of this study was to explore a feasible method for the reconstruction of the nasal and temporal bone structures of the Chinese virtual human project and provide a more accurate and facilitated way view them three-dimensionally (3D). The 3-D Slicer software was used to reconstruct the anatomic structures of the human nose and temporal bone.(More)
OBJECTIVE To study the changes of N-methyl-D-aspartate (NMDA) receptor subunit 2A (NR2A) expression at local synapses in auditory cortices after early postnatal sound insulation and tone exposure. METHOD We prepared highly purified synaptosomes from primary auditory cortex by Optiprep flotation gradient centrifugations, and compared the differences of(More)
This paper presents a novel approach to cross-view action recognition. Traditional cross-view action recognition methods typically rely on local appearance/motion features. In this paper, we take advantage of the recent developments of depth cameras to build a more discriminative cross-view action representation. In this representation, an action is(More)
PURPOSE Image-based tracking for motion compensation is an important topic in image-guided interventions, as it enables physicians to operate in a less complex space. In this paper, we propose an automatic motion compensation scheme to boost image guidence power in transcatheter aortic valve implantation (TAVI). METHODS The proposed tracking algorithm(More)

The adjacent buildings and bridges could be destroyed to different extent, which resulted from earthquake pounding. This paper introduced different contact models and methods employed by researchers at home and abroad, and focused on the 3D contact-friction model of pounding considering tangential friction proposed by PING ZHU, moreover, not only to realize(More)
