项目摘要

Multiview is expected to be the next generation visual communication and multi-view is one of the fundamental problems for various applications such as free viewpoint TV.In free viewpoint video transmission, users can select any view angle he prefers. To provide the free viewpoint selection, server will send the two nearest neighboring view in texture plus depth format upon user’s view request, so that the user can synthesize the view at the requested viewing angle afterwards using the depth image based rendering (DIBR) techniques. To handle the burst-loss prone wireless channels, we proposed to transmit the video contents over two paths after encoding them using the multiple descriptions coding (MDC) for the free viewpoint video streaming. The related results have been accepted to IEEE Journal of Selected Topics in Signal Processing.Orthogonally, battery life consumption is critical for mobile users, how to balance the energy consumption and the received video quality becomes a serious problem. We investigate this problem and publish the results in Journal of Network and Computer Applications.HetNets is a major topic in 4G and 5G. How to deliver the video in the scenarios composed of multiple cells (base station) will be become an important issue. The challenges exist in how to coordinate the intercell inferences given users’ diverse video requests. Some preliminary results have been published in IEEE VTC2014 spring and an extension is under submission.At the same time, we are looking for more applications of the multi-view such as for the museum exhibition.

多视图有望成为下一代视觉通信，而多视图是自由视点电视等各种应用的基本问题之一。在自由视点视频传输中，用户可以选择任何他喜欢的视角，以提供自由的视点选择。，服务器将根据用户的视图请求以纹理加深度格式发送两个最近的相邻视图，以便用户可以随后使用基于深度图像的渲染（DIBR）技术以请求的视角合成视图来处理突发丢失。容易出现无线信道，我们建议通过以下方式传输视频内容使用多描述编码（MDC）对自由视点视频流进行编码后的两条路径相关结果已被IEEE信号处理精选主题杂志接受。正交地，电池寿命消耗对于移动用户至关重要，如何平衡。能源消耗和接收的视频质量成为一个严重的问题，我们研究了这个问题，并将结果发表在《网络与计算机应用杂志》上。HetNets是4G和5G中如何在多个场景中传输视频的一个主要主题。小区（基站）将成为一个重要问题，鉴于用户多样化的视频请求，如何协调小区间推理存在一些初步结果，并且正在提交扩展。，我们正在寻找多视图的更多应用，例如博物馆展览。
