background: little is known about how to introduce complex technologies like arthroscopy into low-income countries. thus, we compared low- versus high-resource intensive methods of teaching basic arthroscopic skills in a randomized controlled trial in haiti. methods: forty-eight haitian orthopaedic surgeons and residents attending an orthopaedic conference in haiti were block randomized to rece...

Most of current video streaming technologies, which protect the video stream by rate allocation or CRC means according to the bandwidth of network and the video quality user expected, is unrelated with the content of video. This paper proposes a new content-based video streaming method, which is based on video content analysis. The method discusses the rate distortion function of Fine Granular ...

An arbitrary resolution video coding method based on compressive sampling is proposed. In this method, a video is coded using compressive measurements. The compressive measurements are made on videos of high resolution. The measurements may be used to reconstruct the video at the same resolution as the original video, and any subset of the measurements can be used to reconstruct video at lower ...

This paper presents a video summarization method to visualizing video sequences in a static image for the purposes of efficient representation and quick overview. It can assist viewers to understand important video contents by revealing essential information of video story units and their relations. We have designed a new method called Video Presentation Board to extract, organize, and synthesi...

in this paper, we propose a new full-fuzzy video ratecontrol algorithm (rca) for variable bit rate (vbr) videoapplications. the proposed rca provides high qualitycompressed video with a low degree computational complexity.by controlling the quantization parameter (qp) on a picturebasis, it produces vbr video bit streams. the proposed rcahas been implemented on the jm h.264/avc video codec andth...
