Abstract
This paper presents a GPU-based spherical coordinate conversion system for panorama video image stitching. Modern programmable GPU makes it possible to process multiple images in an interactive frame rates. To perform image stitching to form a panorama view, we use OpenCL to stitch multiple images and then texture map it to a spherical object. This allows us to compose an immersive environment. In the case study presented in this paper, we achieve a speedup factor of 76x.
