Image-based geometrically-correct photorealisitic scen/object modeling (IBPhM): a review

摘要

There are emerging interests from both computer vision and computer graphics communities in obaining photorealistic mdeling of a scene or an object frm real images. This paper present a tenatative review of the computer vision techniques used in such modeling which guarantee the generated views to be geometrically correct. The topics covered include mosacking for building environment maps, CAD-like modeling for bukding 3D geometric models together with texture maps extracted from real images, image-based rendering for synthesizing new views form uncalibrated images, and techniques for modeling the appearance variation of a scence or an object undr different illumination conditions. Major issues and difficulties are addiressed.
