Image-Based Rendering with Occlusions via Cubist Images

In this paper, we study the idea of IBR based on a flattened, possibly torn, wrap-around texture image (the source image) and the paths in time of camera rays mapped from their 3D scene intersection points to this single warped image. We also investigate the feasibility of sparse spatial camera-ray ...

Stereo photography techniques
Stereo photography techniques are methods to produce stereoscopic images, videos and films. This is done with a variety of equipment including special built stereo cameras, single cameras with or without special attachments, and paired cameras. This involves traditional film cameras as well as, tape and modern digital cameras. A number of specialized techniques are employed to produce different kinds of stereo images.
