Accelerating large graph algorithms on the GPU using CUDA
Pawan Harish,P. J. Narayanan +1 more
TL;DR: This work presents a few fundamental algorithms - including breadth first search, single source shortest path, and all-pairs shortest path - using CUDA on large graphs using the G80 line of Nvidia GPUs.
Journal ArticleDOI
Virtualized reality: constructing virtual worlds from real scenes
TL;DR: In this paper, a new visual medium, Virtualized Reality, immerses viewers in a virtual reconstruction of real-world events, which consists of real images and depth information computed from these images.
Proceedings ArticleDOI
Constructing virtual worlds using dense stereo
TL;DR: The intensity image and depth map for each camera view at each time instant are combined to form a Visible Surface Model, a technique to create virtual worlds out of dynamic events using densely distributed stereo views.
Proceedings ArticleDOI
CUDA cuts: Fast graph cuts on the GPU
Vibhav Vineet,P. J. Narayanan +1 more
TL;DR: This paper presents an implementation of the push-relabel algorithm for graph cuts on the GPU that can perform over 60 graph cuts per second on 1024times1024 images and over 150 graph cutsper second on 640times480 images on an Nvidia 8800 GTX.

Method for creating virtual reality
TL;DR: In this paper, a method of creating virtual reality from images of a real event, is comprised of the steps of capturing a plurality of images of each time instant of real event using a pluralityof cameras positioned at a plurality-of-angles.
