3D SHAPE RECOVERY FROM RANGE IMAGE USING ACTIVE BALLOON MODEL

Abstract

This paper reports the object surface recovery with triangulated patches from a range image. In this case, the recovery must consider its accuracy, reducing the number of the patch, and filling in the holes. One of the remedies for this situation is to generate the patches adaptively depending on the shape variance. However, since the previous adaptive mesh generations use the triangulated image plane, there is the problem that its accuracy depends on the initial triangulation of the plane. In order to solve this problem, this paper presents a new method for reconstructing 3-D object shapes. Our method introduces the active balloon model(ABM)to create the model of the whole surface. Paractically, after creating the rough shape by a new energy function, the shape is changing locally to preserve the geometric features of the object.
