Layered Image Warping Based on Equal-density Mapping and Texture-reconstruction[J]. Journal of image and graphics, 2006, 11(4): 555. DOI: 10.11834/jig.20060492.
Image mapping and image reconstruction are two major components in performing Image warping.Existing reconstruction methods either involve huge computations or tend to produce visual errors in objects appearance using traditional warping model.This article presents a new image warping model by employing a novel "equal-density mapping" and "texture-Reconstruction".With the new model
a layered image mapping(LIW) approach is proposed then.In LIW
reference pixels are firstly mapped to "equal density layers" that parallel the desired view and are stored in a bidirectional link list after some by-layer processing.By implementing post-texture rendering along the list eventually
the warping is transformed to a fast texture mapping process
which provides a considerable speedup.Also
LIW is proved to efficiently tickle the "rubber sheet" problem without any pre-process.
