| Summary: | 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.
