Abstract

Designing interactive segmentation methods for digital volume images is difficult, mainly because efficient 3D interaction is much harder to achieve than interaction with 2D images To overcome this issue, we use a system that combines stereo graphics and haptics to facilitate efficient 3D interaction We propose a new method, based on the 2D live-wire method, for segmenting volume images Our method consists of two parts: an interface for drawing 3D live-wire curves onto the boundary of an object in a volume image, and an algorithm for connecting two such curves to create a discrete surface.
