Three-dimensional propagation algorithm for depth image-based rendering
Depth image based rendering (DIBR) is the process of synthesizing new ``virtual'' views from a set of ``real'' views which include color and depth images. Because of its photorealism and less stringent computational requirement, DIBR has many applications such as 3D TV, remote reality, and video …

Digital Watermarking for Depth-Image-Based Rendering 3D Images and Its Application to Quality Evaluation
… a consequence, the digital watermarking for 3D image and video is attracting considerable attention. The depth-image-based rendering (DIBR) technique has been playing a critical role in 3D contents representation because of its numerous advantages. A good digital watermarking algorithm should be …

Vision-Based Rendering: Using Computational Stereo to Actualize IBR View Synthesis
Computer graphics imagery (CGI) has enabled many useful applications in training, defense, and entertainment. One such application, CGI simulation, is a real-time system that allows users to navigate through and interact with a virtual rendition of an existing environment. Creating such systems is …

Accelerated volumetric reconstruction from uncalibrated camera views
While both work with images, computer graphics and computer vision are inverse problems. Computer graphics starts traditionally with input geometric models and produces image sequences. Computer vision starts with input image sequences and produces geometric models. In the last few years, there has …
