Using Multi - view Video Coding
We propose a video communication method that lets the user freely change his/her viewing position and viewing direction. Free-viewpoint video is a next-generation visual application that has been extensively studied and discussed by the international MPEG standard body as 3DAV (three-dimensional audio and visual). For this application, we propose a multi-view video coding method and communicati...
متن کاملCompression Algorithm for Multi-view Video Coding Using a Depth Map
In this paper, we propose an efficient multi-view video coding algorithm that uses a depth map. This algorithm is based on the correlation between texture maps and depth maps. This correlation is based on the fact that the motion vectors (MVs) in texture maps are strongly affected by their depth values. In general, background objects have smaller MVs whereas foreground objects have higher MVs. ...
متن کاملDistributed Multi-view Video Coding
There are mainly two key points which can affect the efficiency of multi-view video capture and transmission system largely: communication between cameras and computing complexity of encoder. In this paper, we propose a practical framework of distributed multi-view video coding, in which inter-camera communication is avoided and the large computing complexity is moved from encoder to decoder. I...
متن کاملMultiple-view Video Coding Using Depth Map in Projective Space
In this paper a new video coding by using multiple uncalibrated cameras is proposed. We consider the redundancy between the cameras view points and efficiently compress based on a depth map. Since our target videos are taken with uncalibrated cameras, our depth map is computed not in the real world but in the Projective Space. This is a virtual space defined by projective reconstruction of two ...
متن کاملMulti-view dense depth map estimation
A novel dense depth map estimation algorithm is proposed in order to meet the requirements of N-view plus N-depth representation, which is one of the standardization efforts for the upcoming 3D display technologies. Hence, extraction of multiple depth maps is achieved from multi-view video. Starting from the piecewise planarity assumption of the scene, estimation of 3D structure of the patches,...
