| Abstract | ||||
| In this paper, the point is to give steady shadows amongst virtual and genuine objects for outdoor scene without requiring any earlier data. The technique gives a real-time framework for recreating reliable virtual shadows in an outdoor scene. The proposed procedure firstly handles the shadow areas because of genuine things; secondly ensures the pixels in genuine shadow are prevented from more rendering and finally rendering shadows because of virtual things. The main research contribution, in addition to shadow refinement, is handling the overlap between real and virtual shadows. Consequently those shadows for virtual things are depend on the shadows of real things. The experimental results create the impression that the recommended system has basically upgraded that authenticity about steady outside augmented reality rendering, in this manner taking care of the issue of practical augmented reality frameworks. Results show a comparison of shadow rendering between proposed technique and other techniques in different resolutions. | ||||
