A better understanding of human interactions in videos can be achieved by simultaneously considering the coarse interactions between people, the action of each individual, and the activity of all people as a whole. We divide the recognition task into two stages. The first stage discriminates interactions and noninteractions, actions and activities based on local image information, while during the...
Nowadays, the methods and tools of the 3D technology and human body modeling are developed rapidly, learning and analyzing 3D body scans will accelerate the development of 3D modeling. In this research, a novel algorithm using intersection views is proposed for retrieving 3D body scans. An Asian Female Body Scan (AFBS) database is established by analyzing various 3D body scan data at first, and then,...
Key frame selection is important to dense 3D reconstruction, especially for unordered image sets. A novel method for key frame selection from unordered image sets is proposed based Distance Depedent Chinese Restaurant Process (DDCRP). First, a bag-of-features word package is constructed to describe each image in a document-like manner, which can be dealt with by the DDCRP model. Second, the overlapping...
