2D-3D Automatic Mesh Generation
  • 2D-3D Automatic Mesh Generation
www.hpfem.jku.at
NETGEN is an open source automatic mesh generation tool for two and three dimensions. It comes as a stand alone program with graphical user interface, or as a C++ library to be linked into an other application. Netgen is available for Unix/Linux and Windows 98/NT. Netgen generates triangular or quadrilateral meshes in 2D, and tetrahedral meshes in 3D....

A New Grey-Scale Template Image Matching Algorithm Using the Cross-Sectional Histogram Correlation Method
  • A New Grey-Scale Template Image Matching Algorithm Using the Cross-Sectional Histogram Correlation Method
www.math.ucla.edu
A new correlation technique for Grey-Scale Template Image Matching, the Cross-Sectional Histogram Correlation (CHC) Method, is proposed. In comparison to the traditional, widely-used Normalized Grey-Scale Correlation (NGC) Method, the CHC Method is computationally inexpensive and more robust against image noise....

Div, Grad, Curl, and All That: An Informal Text on Vector Calculus
  • Div, Grad, Curl, and All That: An Informal Text on Vector Calculus
www.books-by-isbn.com
When I started reading about level set methods, I realized that I must have strong mathematical background in several math areas such as differential geometry, vector calculus, partial differential equations, etc. But most importantly, i need to understand the logical/physical meaning of several math terms such as the gradient, divergence, laplacian, etc....

On the implementation of fast marching methods for 3D lattices
  • On the implementation of fast marching methods for 3D lattices
www2.imm.dtu.dk
This technical report discusses Sethian's Fast Marching Method and its higher accuracy variant. Both methods may be used to compute the arrival times at the points of a discrete lattice of a front which is monotonously expanding. Applications of the method include arrival time computation and the construction of distance fields for 2D or 3D objects....

Writing Fast Matlab Code
  • Writing Fast Matlab Code
www.math.ucla.edu
This article discusses strategies for improving the speed of Matlab code. Keep in mind that speed depends heavily on the computation platform and that the fastest method on one system is not necessarily the fastest on another. Second, Matlab has gone through many version and continues to evolve: a slow method may become fast in a newer version....

On the Extraction of Curve Skeletons using Gradient Vector Flow
  • On the Extraction of Curve Skeletons using Gradient Vector Flow
mecca.louisville.edu
In this paper, we propose a new variational framework for computing continuous curve skeletons from discrete objects that are suitable for structural shape representation. We have derived a new energy function, which is proportional to some medialness function, such that the minimum cost path between any two medial voxels in the shape is a curve skeleton....

Active Contours Without Edges and Image Segmentation
  • Active Contours Without Edges and Image Segmentation
www.math.ucla.edu
This report will consider one recent method of solving the image segmentation problem, namely, the Active Contour Without Edges method. This method utilizes the level set technique of curve treatment and more importantly, overcomes several difficulties arising in previous methods of image segmentation. Most part of this report follows that of Chan and Vese....
