With the recent explosive growth of Augmented Reality (AR) and Virtual Reality (VR) platforms, technology to capture and render dynamic physical space has increasingly become indispensable. In this paper, we present a novel system that can capture and render in real-time dynamic 3D scenes on a virtual arbitrarily-shaped curved mirror. To achieve a realistic mirror rendering, the reflective scenes...
A novel subpixel rendering algorithm for diamond-shaped PenTile displays, which improves the apparent display resolution and reduces color fringing artifacts, is proposed in this work. We develop two types of filters: main filters and nonnegative filters. First, the main filters are derived to minimize the error between an original input image and a perceived image. Second, the nonnegative filters...
With the advance of multimedia technology, traditional remote communication applications (e.g. video chat) may not satisfy the increasing demand for effective interactivity due to the lack of realistic experience of being physically present. Telepresence is a new form of communication that aims to strengthen the connection between people by creating more immersive and interactive environments. However...
The subpixel rendering is attractive in that it improves effective resolutions of displays by processing at the subpixel level. But it lies on a risk of chrominance error called color fringing effect while restoring the degraded shape of restrictive resolution. We propose a filter design method for subpixel rendering. We first generate a virtual image model, which describes how human visual system...
We propose a novel hybrid representation scheme for indoor environments using meshes and point clouds. Points are suitable for rendering detailed objects, while meshes can represent planar shapes more compactly. Based on these properties, we use points or meshes adaptively according to local characteristics of an input scene. More specifically, we first determine building structures, which can be...
A virtual view synthesis algorithm using multi-view video sequences, which inherits the advantages of both the forward warping and the inverse warping, is proposed in this work. First, we use the inverse warping to synthesize a virtual view without holes from the nearest two views. Second, we detect occluded regions in the synthesized view based on the uniqueness constraint. Then, we refine the occluded...
