碩士 === 國立交通大學 === 資訊科學學系 === 86 === In recent years, image-based rendering becomes an important technique invirtual reality system. It can generate photo- realistic images interactively.Among all image-based virtual environment systems, however, there is one majordeficiency - the lack of perspective perception. Because of the loss of depthinformation, users may not have truly immersive feelings when walkthrough inthe scene. In this thesis, we extract the foreground object images from theoriginal panoramic image. When walking through in the system, users can feelthat the foreground objects are in front of the background, and provideperspective perception more strongly.
