A 3D Live-Wire Segmentation Method for Volume Images Using Haptic Interaction
نویسندگان
چکیده
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.

Segmentation and Visualization of 3D Medical Images through Haptic Rendering
High-dimensional and high-resolution image data is increasingly produced by modern medical imaging equipment. As a consequence, the need for efficient interactive tools for segmentation and visualization of these medical images is also increasing. Existing software include state-of-the-art algorithms, but in most cases the interaction part is limited to 2D mouse/keyboard, despite the tasks bein...

متن کاملLive-Wire Revisited
The live-wire approach is an interactive, contour-based segmentation technique. Generally, the contour of a targeted object (anatomical structure) is built by interactively selecting control points and finding minimal-cost paths between them. By its very nature, this method is applicable only to 2D images. For the segmentation of 3D datasets (volumes), the interactive generation of live-wire co...

We present a fast and accurate tool for semiautomatic segmentation of volumetric medical images based on the live wire algorithm, shape-based interpolation and a new optimization method. While the user-steered live wire algorithm represents an efficient, precise and reproducible method for interactive segmentation of selected twodimensional images, the shape-based interpolation allows the autom...
متن کاملInteractive segmentation of image volumes with Live Surface
Live Surface allows users to segment and render complex surfaces from 3D image volumes at interactive (sub-second) rates using a novel, cascading graph cut (CGC). Live Surface consists of two phases. (1) Preprocessing for generation of a complete 3D hierarchy of tobogganed regions followed by tracking of all region surfaces. (2) User interaction in which, with each mouse movement, the volume is...
