Many applications for 3d object analysis and visualization need to deal with object features. The most common features on triangulated surfaces are ridges and valleys which are interesting for matching, segmentation, smoothing, non-photo-realistic rendering and many other tasks. In some cases these features are interrupted or corrupted otherwise. In this paper we present an approach to close such gaps in feature regions. For this purpose a vectorfield on the surface, based on the detected features, is computed. The analysis of this vector field yields to possible junction points. These junction points are connected (guided by the vector field) to close the interrupted feature regions.:1 INTRODUCTION 2 RELATED WORK 3 BASIC DEFINITIONS AND NOTATIONS 4 DETECTION OF FEATURE REGIONS 5 PRE-PROCESSING STEPS 6 CONNECTING FEATURE REGIONS 7 EVALUATION 8 FEATURE RESEARCH
