3D Modelling from Multiple Views Using Iterative Paper No. 53

Summary: 1
3D Modelling from Multiple Views Using Iterative
Node Cut
Paper No. 53
In this paper, we present an approach to model three-
dimensional (3D) object given its images acquired from dif-
ferent viewpoints. The generated model includes both shape
and color information of the object so that it can be used
not only to make 3D measurements but also to render new
views of the object. We first construct a 3D voxel space and
assign to each voxel a photo-inconsistency value, and then
represent this voxel space using a node-capacitated graph.
We iteratively use s-t node cut to obtain a surface that min-
imizes the summation of photo-inconsistency values of sur-
face voxels. In addition, we present a method to obtain
surface constraints from silhouette information in the input
images. These surface constraints ensure that the obtained
object surface is consistent with the silhouettes in all input
images and help the proposed iterative node cut algorithm
