Simultaneous double video mediastinoscopy and video mediastinotomy—a step forward☆

Video Art, Liminality, Mysticism

Liminality is a concept introduced by Victor Turner in the field of anthropology. According to him, myths can be designated as liminal phenomena which are neither here nor there; they are betwixt and between. Bill Viola is a video artist who has represented universal and pivotal dualities in his work, in a symbolic manner. The questions that this study tries to answer are as follows: What is th...

An Improved Motion Vector Estimation Approach for Video Error Concealment Based on the Video Scene Analysis

In order to enhance the accuracy of the motion vector (MV) estimation and also reduce the error propagation issue during the estimation, in this paper, a new adaptive error concealment (EC) approach is proposed based on the information extracted from the video scene. In this regard, the motion information of the video scene around the degraded MB is first analyzed to estimate the motion type of...

Forward Error Correction for Video Coding

Joint source-channel coding solutions has proved to provided better performance than dealing with both coding processes separately. Such improvement is achieved by jointly minimizing at the source encoder the channel effects. In this paper, we present an adaptive scheme for forward error protection of any video coding standard. The channel coding rate changes according to the channel bit error ...

Distributed Video Streaming with Forward Error Correction

With the explosive growth of video applications over the Internet, many approaches have been proposed to stream video effectively over packet switched, best-effort networks. Many use techniques from source and channel coding, or implement transport protocols, or modify system architectures in order to deal with delay, loss, and time-varying nature of the Internet. In our previous work , we prop...
