In this document we present additional results for the paper of Mattausch et al. [MIW13]. In particular, we compare silhouette computation methods used as input for the shadow editing algorithm, show some additional editing and animation examples, and show the effect of the ε parameter of the modified shadow volumes which takes a silhouette vertex so to so. 1 Silhouette Computation A comparison...

This paper presents an approach for recognizing urban scene in distant views. Previously, we have developed a method using dynamic programming technique to recognize key buildings appearing as silhouette in a distant view. Based on those locations of buildings in silhouette, this paper develops a method to find locations of other buildings which do not appear as silhouette in the image by using...

Abstract: A new graphical display is proposed for partitioning techniques. Each cluster is represented by a so-called silhouette, which is based on the comparison of its tightness and separation. This silhouette shows which objects he well within their cluster, and which ones are merely somewhere in between clusters. The entire clustering is displayed by combining the silhouettes into a single ...

OBJECTIVES To compare pairs of silhouettes generated from presurgical and 5-year postsurgical cephalometric radiographs to evaluate whether orthodontists, oral surgeons, and lay persons perceive changes in profile resulting from orthodontics and mandibular advancement surgical treatment. MATERIALS AND METHODS A survey-based method of data collection was used to evaluate 15 pairs of silhouette...

part of artistic expression (for example, any pencil or pen-and-ink drawing), scientific illustrations (medical or technical), or entertainment graphics (such as in comics). Hence, computer graphics researchers have extensively studied the automatic generation of such lines. In particular, the area of nonphotorealistic rendering has focused on two main directions of research in this respect: th...

This paper presents a novel approach for silhouette extraction from multi-viewpoint images. The main contribution of this paper is a new algorithm for 1) 3D context-aware error detection and correction of 2D multi-viewpoint silhouette extraction and 2) 3D context-aware classification of castshadow regions. Some experiments demonstrate advantages against previous approaches.

The idea of photometric stereo is to serially vary the direction of incident illumination on the state of the holded view point, but it can locally reconstruct only the front surface to a view point. However the silhouette informations obtained by plural viewing directions provide the entire 3D structure of an object surface, but the 3D information of the region whose edge is unexposed to the v...
