✦ Synopsis

In order to construct a 3D model from a collection of 2D images of an object, an energy function is defined between the object's images and corresponding images of an articulated mesh in three dimensions.

Repeated adjustment of the mesh to minimize the energy function results in a mesh that produces images which closely approximate the input images, that is to say that under the appropriate conditions it realizes a preconceived object. It has implications for model building, reverse engineering and computer vision. Minimization of the energy function is a multivariate problem of large scale with many local minima. We give an approach for solving this problem. For certain restricted, but useful applications, intuitive solutions to the minimization are consistently obtained. $
