Interactive Volume Cutting
Abstract
In 2D, Intelligent Scissors is an efficient interactive tool for image
segmentation. By interactive use of a dynamic-programming graph-searching
algorithm, a region of interest in the image can be accurately obtained.
In this paper, we introduce the use of Intelligent Scissors for contour
detection on a volumetric data surface. It is fast enough to be used in
an interactive virtual environment, in which the user can intuitively
select the contours in volumetric data in an accurate and robust manner.
Moreover, we extend our work to the volume data manipulation,
cutting off the interesting part of the volume by providing a contour
on its surface. The cutting surface is computed by a fast dynamic
programming algorithm. By using this tool, many new volumetric data models
can be created from an existing one in an effective way.
