dc.description.abstract-translatedIn computer graphics, the generalized barycentric coordinates (GBC) are often used for image deformation. To manipulate an input image using a cage based image deformation method, we usually have to consider a source polygon with a triangulation; but defining the triangulation of the source polygon is not a trivial task in most cases. In this paper, a uniform and a non-uniform triangulation technique—which can be the basis of the cage based image deformation—are introduced and compared. Moreover, different texture filtering methods are tried, producing various deformation results. Experimental results and demonstrative pictures show the behaviors of the triangulation methods.en
