Abstract

This paper proposes a method to segment a set of models consistently. The method simultaneously segments models and creates correspondences between segments. First, a graph is constructed whose nodes represent the faces of every mesh, and whose edges connect adjacent faces within a mesh and corresponding faces in different meshes. Second, a consistent segmentation is created by clustering this graph, allowing for outlier segments that are not present in every mesh. The method is demonstrated for several classes of objects and ...

Abstract

In the past few years, there has been an increasing availability of technologies for the acquisition of digital 3D models of real objects and the consequent use of these models in a variety of applications, in medicine, engineering, and cultural heritage. In this framework, content-based retrieval of 3D objects is becoming an important subject of research, and finding adequate descriptors to capture global or local characteristics of the shape has become one of the main investigation goals. In this article, we ...

Abstract

Classification of CAD helps the reuse of engineering designs and accelerates product development. Existing research, based on either group technology or fixed modeling matching algorithms, impose a priori categorization schemas on engineering data or require significant human labeling. This research introduces a framework for automatic classification of CAD models using a pattern classification model. It separates feature extraction and classification from 3D shape matching procedures. Different shape features and classifiers can be incorporated to fit example CAD/CAM oriented classification schemas. Two ...
