Free Viewpoint Video Based on Stitching Technique

Abstract

Image stitching is a technique used for creating one panoramic scene from multiple images. It is used in panoramic photography and video where the viewer can only scroll horizontally and vertically across the scene. However, stitching has not been used for creating free-viewpoint videos (FVV) where viewers can change their viewing points freely and smoothly while playing the video. current research, implemented FVV playing system using image stitching, this system allows users to enjoy the capability of moving their viewpoint freely and smoothly. To develop this system, user should capture MVV from different viewpoints and with appropriate region area for each pair of cameras then the system stitch the overlapped video to create stitched video/videos to display it in FVV playing system with applying freely and smoothly switching and interpolation of viewpoints over video playback. Current research evaluated the performance of video playing system based on system idea, system accuracy, smoothness, and user satisfaction. The results of evaluation have been very positive in most aspects.
