Motion capture is an important technique with a wide range of applications in areas such as computer vision, computer animation, film production, and medical rehabilitation. Even with the professional motion capture systems, the acquired raw data mostly contain inevitable noises and outliers. To denoise the data, numerous methods have been developed, while(More)
Since each visual feature only reflects a unique characteristic about a 3-dimensional (3D) model and different visual features have diverse discriminative power in model representation, it would be beneficial to fuse multiple visual features in 3D model retrieval. To this end, we propose a fast view-based 3D model retrieval framework in this article. This(More)
A novel copper-catalyzed cascade difluoromethylation/cyclization of 2-(3-arylpropioloyl)benzaldehydes has been developed. This method affords an efficient and straightforward access to structurally diverse difluoromethylated naphthoquinones in one pot, starting from readily available starting materials. The reaction represents the first(More)
Based on the extracted contours of objects from images, one point to point (P2P) method is proposed for shape matching and image retrieval. Taking contour of one object as reference, contour of another object is transformed to reach their best match, during which the similarity is evaluated by comparison of two corresponding sets of contour points.(More)
