Marching Optimal-Parameter Ridges: An Algorithm to Extract Shape Loci in 3D Images
نویسندگان
چکیده
This paper presents a method for identifying image loci that can be used as a basis for object segmentation and image registration. The focus is on 1D and 2D shape loci in 3D images. This method, called marching ridges, uses generalized height ridges, oriented medialness measures and a marching cubes like algorithm to extract optimal scale-orientation cores. This algorithm can can also be used for other image processing tasks such as nding intensity skeletons of objects and identifying object boundaries.

Marching ridges
Marching Ridges is an algorithm for finding ridges of measurement functions defined for images, in which the ridges are defined as level sets of first derivatives of the measurement functions. Marching Ridges is both specific in its application to 2D and 3D medical images for the purpose of finding cores, and general in its theoretical application to finding ridges of intensity, boundary and me...
متن کاملDetermining optimal value of the shape parameter $c$ in RBF for unequal distances topographical points by Cross-Validation algorithm
Several radial basis function based methods contain a free shape parameter which has a crucial role in the accuracy of the methods. Performance evaluation of this parameter in different functions with various data has always been a topic of study. In the present paper, we consider studying the methods which determine an optimal value for the shape parameter in interpolations of radial basis ...
متن کاملTuning Shape Parameter of Radial Basis Functions in Zooming Images using Genetic Algorithm
Image zooming is one of the current issues of image processing where maintaining the quality and structure of the zoomed image is important. To zoom an image, it is necessary that the extra pixels be placed in the data of the image. Adding the data to the image must be consistent with the texture in the image and not to create artificial blocks. In this study, the required pixels are estimated ...

This paper presents a powerful and general purpose tool designed to extract characteristic lines from 3D images . The algorithm, called Marching Lines, is inspired from the Marching Cubes algorithm, which is used to extract iso-value surfaces from 3D images. The Marching Lines algorithm extracts with sub-pixel accuracy the 3D lines corresponding to the intersection of two iso-surfaces from two ...
متن کاملComputing geodesic paths on triangulated manifolds
Solving the Eikonal equation on a surface allows establishment of a curvilinear coordinate system which facilitates many types of physics-based simulations and measurements. Existing methods that solve the Eikonal equation on surface triangulations suffer from significant limitations prohibiting their use in many applications. First, the surface may not have any holes. Second, every obtuse tria...
