Dong Min Kim (Dane) Writing 340 Illumin Article June-12-2013 Abstract Building a house using 3-D printing technology is available to people in near future. Contour crafting is the method that can build a house quickly, safely, and economically. Since the robots and computers are the main part of the construction, human labor restriction that causes expensive and inefficient construction will be...

A new approach for contour data approximation and compression algorithm is presented in the paper. Cartesian co-ordinates of an input contour are processed in such a manner that finally contours is presented by selected vertices of the edge of the contour. In the paper the main idea of the proposed procedure and compression of analysed method with the Ramer and the Tangent methods of contour ap...

An extension of the contour integral method (CIM) for the computation of stress intensity factors for loaded cracks is presented. Numerical solutions of the two-dimensional linear elasticity equations are computed with the p-version of the generalized finite element method. Polynomial enrichment functions as well as enrichment with near crack tip asymptotic expansion are used. The robustness of...

Active contour models are widely used for image segmentation. In this paper the study of various active contour models based on Chan-Vese approach is given. Partial differential equation based method widely used on real and artificial noisy images with different shapes and blurring boundaries and energy minimization has been achieved. The possibilities of extracting exact contour using these me...

A new method for characterizing complex irregular shapes of natural objects (e.g. plant cells, aerosol particles) is presented. The method employs complex Fourier analysis rather than the traditional forms of the Fourier analysis. Digitized images of objects are processed and the contours are tracked by a classical boundary following technique. A new contour preprocessing technique allows to no...

The active contour is an effective method to perform image segmentation. But its key technology problem is, both the establishment of a mathematic model and the development of the calculating algorithm are excessively dependent on the initial contour position. In dynamic image analysis, the difference method and the fast template matching algorithm provide available solutions for dealing with t...

This paper describes a new, high-speed contourf i l l method for alpha-numeric and Japanese Kanji characters developed to generate digital bitmap image (binary image) patterns from contour lines. The contour lines are expressed by Freeman's chain code. We call this method the Improved Edge-flag method. The speed of this method is increased by using an edge-flag list which stores the coordinates...

We propose an exemplar-based tracking framework for human contour tracking. The exemplars, i.e. the contour representatives, are used to construct a contour ensemble. The main task of contour ensemble is to generate contours to fill in the gaps in-between in the test sequences, and to supply the dynamics for updating the target contour by fast contour query. As a result, a normal dynamic Bayesi...
