Flux driven automatic centerline extraction
We present a fast, robust and automatic method for computing centerline paths through tubular structures for application to virtual endoscopy. The key idea is to utilize a skeletonization algorithm which exploits properties of the average outward flux of the gradient vector field of a Euclidean distance function from the boundary of the structure. The algorithm is modified to yield a collection...
متن کاملNear Real-time Road Centerline Extraction
In this paper a new GPS/INS/CCD integrated system for precise monitoring of highway center and edge lines is presented. The system has been developed at The Ohio State University (OSU) for the Ohio Department of Transportation (ODOT). The positioning component of the system is based on tightly integrated GPS/INS (dual frequency GPS receiver and a high-accuracy strapdown INS), and the imaging co...
متن کاملParallel centerline extraction on the GPU
Centerline extraction is important in a variety of visualization applications including shape analysis, geometry processing, and virtual endoscopy. Centerlines allow accurate measurements of length along winding tubular structures, assist automatic virtual navigation, and provide a path-planning system to control the movement and orientation of a virtual camera. However, efficiently computing c...
متن کاملAn algorithm for centerline extraction using natural neighbour interpolation
Data caption and conversion are two of the most costly operations of any GIS, in terms of computer time and manual work needed for spatial data acquisition. They can represent up to 80 percent of the total implementation costs. Manual digitising is a very error prone and costly operation, especially due to the lack of explicit topology in commercial GIS systems. Indeed, each map update might re...
متن کامل3-d Centerline Extraction of Axons in Confocal Microscopic Stacks
Extraction of geometrical features of biological structures is an active research topic. Accurate tracking algorithms provide valuable quantitative data which not only helps reduce manual labor, but also helps biologists answer a range of basic-science questions. This thesis presents a hybrid algorithm for the centerline extraction of axons in a stack of cross-sectional images acquired from a l...
