Planar parameterization for closed 2-manifold genus-1 meshes

Planar parameterization for closed 2-manifold genus-1 meshes

Ninth ACM Symposium on Solid Modeling and Applications, SM'04

作者： Steiner, D. Fischer, A. Laboratory for Computer Graphics and CAD Faculty of Mechanical Engineering Technion - Israel Institute of Technology Haifa 32000 Israel

Parameterization of 3D meshes is important for many graphics and CAD applications, in particular for texture mapping, re-meshing and morphing. Current parameterization methods for closed manifold genus-n meshes usually involve cutting the mesh according to the object generators, fixing the resulting boundary and then applying the 2D position for each of the mesh vertices on a plane, such that the flattened triangles are not too distorted and do not overlap. Unfortunately, fixing the boundary distorts the resulting parameterization, especially near the boundary. A special case is that of closed manifold genus-1 meshes that have two generators. They can therefore be flattened naturally to a plane without the use of a fixed boundary while still maintaining the continuity of the parameterization. Therefore, in treating genus-1 objects, this attribute must be exploited. This paper introduces a generalized method for planar parameterization of closed manifold genus-1 meshes. As in any planar parameterization with a fixed boundary, weights are assigned over the mesh edges. The type of weights defined depends on the type of mesh characteristics to be preserved. The paper proves that the method satisfies the non-overlapping requirement for any type of positive barycentric weights, including nonsymmetrical weights. Moreover, convergence is guaranteed according to the Gauss-Seidel method. The proposed method is simple to implement, fast and robust. The feasibility of the method will be demonstrated on several complex objects.

International Conference on Shape Modeling and Applications

作者： B. Lipshitz A. Fischer Laboratory for Computer Graphics and CAD Department of Mechanical Engineering Technion-Israel Institute of Technology Haifa Israel

The manufacturing industry constantly needs to verify machined objects against their original CAD models. Given a prototype design, an engineer should be able to determine whether the part was manufactured well, that is, whether it fits the CAD model exactly. However, derivative computations are unstable for real data, and the estimated curvature is thus very sensitive to noise. Moreover, in many cases, spatial fitting of corresponding points is not sufficient. The current work utilizes the curvature properties to inspect a manufactured part.

International Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems (HAPTICS)

This paper presents a fast haptic rendering method providing the sense of touch from a virtual volumetric non-rigid object when a human operator interacts with the object at multiple points. Previously, we have proposed a fast volume haptic rendering method based on the shape-retaining chain linked model (or the S-chain model) that can handle the deformation of a volumetric non-rigid object and its haptic feedback in real time. One of the key differences between the S-chain model and a traditional FEM or mass-spring model is that the computation of the deformation and its reflected force is performed at a local level. When there are more than one interaction points with the object, it is necessary to consider a modeling framework that can handle human operator's all inputs together. In this paper, we propose a modeling framework in which forces generated at interaction points are vectorially summed to deal with the multiple contact points. Our experiments demonstrate that our proposed method is suitable for the real-time volume haptic rendering of a volumetric non-rigid object with multiple-contact points.

Computationally efficient and reliable fingerprint mosaicking on embedded hardware using minutiae

Machine graphics and Vision 2004年第4期13卷 401-415页

Fingerprint matching is a common technique for biometric authentication. Solid state sensors allow the use of fingerprint recognition in small sized embedded systems. The size of these sensors makes it necessary to store several impressions of the same finger to provide good coverage of the entire fingertip. In order to reduce memory requirements and matching time all these impressions can be fused into a single larger image. Memory constraints imposed by embedded computers prohibit the use of images. A fingerprint is therefore represented as a set of minutiae coordinates and minutiae angles. We present a two stage approach to combine two fingerprints. First, a RANSAC based method is used to determine a rigid transformation which roughly aligns the two fingerprints. Second, the transformation is optimised using a robust least median of squares solution. The reliability of the method is demonstrated on a large synthetic dataset and real fingerprint images. The computational complexity and memory requirements allow implementation of the algorithm on embedded hardware.

Simulation accuracy of a methodology for composable modeling of microelectromechanical systems (MEMS) is assessed by comparing against analytic equations and finite element simulations. Several MEMS canonical problems are composed hierarchically as networks of simple elements with models written in an analog hardware description language. Schematics built from this model library, called NODAS (nodal design of actuators and sensors), produce DC simulation results that are accurate to at least three digits, demonstrating suitable accuracy and lumping trade-offs. © 2003 IEEE.

Surface Reconstruction of Freeform Objects Based on Multiresolution Volumetric Method

Journal of Computing and Information Science in engineering 2003年第4期3卷 334-338页

Recently developed 3D scanning devices are capable of capturing point clouds, as well as additional information, such as normals and texture. This paper describes a new and fast reverse engineering method for creating a 3D computerized model from data captured by such contemporary 3D scanning devices. The proposed method aggregates large-scale 3D scanned data into an extended Hierarchical Space Decomposition Model (HSDM) based on Octree data structure. This model can represent both an object’s boundary surface and its interior volume. The HSDM enables data reduction, while preserving sharp geometrical features and object topology. As a result the execution time of the reconstruction process is significantly reduced. Moreover, the proposed model naturally allows multiresolution surface reconstruction, represented by a mesh with regular properties. Based on the proposed volumetric model, the surface reconstruction process becomes more robust and stable with respect to sampling noise.

作者： D. Taubman R. Rosenbaum School of Electrical Engineering and Telecommunications The University of NSW Sydney Institute of Computer Graphics University of Rostock Germany

This paper is concerned with remote browsing of JPEG2000 compressed imagery. A potentially interactive client identifies a region and maximum resolution of interest. The server responds by sending information from the JPEG2000 code-stream which is relevant to this region and resolution. We propose an algorithm for sequencing data from the original code-stream in such a way as to maximize the received image quality within the region of interest, at each point in the transmission. The proposed R-D optimal sequencing algorithm is demonstrated in the context of two quite different client-server paradigms, one of which is consistent with the evolving JPIP (JPEG2000 Internet protocols) standard. Performance improvements as large as 8 dB are achieved with respect to a layer progressive sequencing strategy.
