Abstract

Consistent illumination plays very important role in efficient integration of virtual objects into real world scene. Real time photometric registration requires efficient detection and segmentation of the brighter regions in an image to provide better light source detection and thus efficient illumination of virtual objects is possible. The paper presents a technique for light source sampling of images taken through a fish-eye Camera. These images taken through this Camera are sampled using improved variance-cut algorithm. The technique helps to detect the brighter region efficiently. With deferred rendering, some experimental results demonstrate that the proposed method produces plausible AR visualization
