This paper presents a framework which allows urban planners to navigate and interact with large datasets fused with social feeds in real-time, enhanced by a virtual reality (VR) capability, which further promotes the knowledge discovery process and allows to interact with urban data in natural yet immersive way. A challenge in urban planning is making decisions based on datasets which are many times...
This paper presents a new stereo matching algorithm to compute dense disparity map for virtual view synthesis. The reference view is segmented using mean-shift segmentation method. An adaptive support-weights window-based approach is adopted to obtain the initial disparity map per pixel. We utilize cross-checking technique to filter out reliable correspondences and detect occlusion regions. The disparity...
A new 3-D data representation format consisting of monoscopic color video and its associated per-pixel depth information is a most promising technique applied in future three-dimensional television system. Despite many advantages of this representation, a large problem which is so-called disocclusion still exists when synthesizing one or more virtual views of a real-world scene by means of depth image...
Generating virtual views is one of the crucial problems for a free-viewpoint video system. In this paper, we solve the problem by using a method based on the technique of view morphing, and construct a multi-camera based experimental free-viewpoint video platform to validate its feasibility. This method requires no setting up of dense cameras, therefore the system is easy to be established and controlled...
