In this letter, we propose a cross-view down/up-sampling (CDU) method for the framework of reduced resolution multiview depth video coding, which exploits cross-view information to assist the up-sampling at the decoder. In the down-sampling procedure of CDU, the odd-even interlaced extraction is employed to preserve more confident information of the original depth video with reduced resolution. In...
The coding efficiency improvement of stereoscopic video system is a hot research topic in the 3D video coding areas. To better exploit the redundancy between the two channels of stereoscopic video, a stereoscopic video coding scheme for Audio Video Coding Standard (AVS) is proposed in the paper. The superior coding performance of the proposed scheme benefits from an enhanced block prediction algorithm,...
With the coming of information age and the extensive application of virtual reality technology, there is a growing concern to e-learning. In the field of virtual reality technology, 3D e-learning for children is becoming a hot topic. In recent years, traffic accidents occur frequently in China, causing a large number of casualties and property losses. Because of children's special characteristics,...
This paper presents a tool and a novel fast invariant transform (FIT) algorithm for language independent e-documents access. The tool enables a person to access an e-document through an informal camera capture of a document hardcopy. It can save people from remembering/exploring numerous directories and file names, or even going through many pages/paragraphs in one document. It can also facilitate...
