Abstract. Shape-from-Silhouette (SFS) is a technique for estimating the shape of an object from images of its silhouette. It is a simple but effective technique for obtaining a three-dimensional (3D) model of an object by using two-dimensional (2D) images of the object in different views. One of its applications is for product presentation in e-commence, in which a 3D model combined with the object’s texture (called 3D color model hereafter) is presented to replace traditional 3D visualization. In 3D visualization, multiple 2D images showing different viewing angles are integrated and a 2D image at a given angle can be displayed via a viewing interface. However, the orientating process is not fluent owing to limited angles recorded. A 3D color model can be displayed alone via a browser or it can be combined with 3D visualization to display the 3D model and 2D images alternatively. The generation of a suitable 3D model from images of multiple views is the very fundamental work as it can affect the success of the later process significantly.
