3D GrabCut: Interactive Foreground Extraction for Reconstructed 3D Scenes
In the near future, mobile devices will be able to measure the 3D geometry of an environment using integrated depth sensing technology. This technology will enable anyone to reconstruct a 3D model of their surroundings. Similar to natural 2D images, a 3D model of a natural scene will occasionally contain a desired foreground object and an unwanted background region. Inspired by GrabCut for stil...
متن کاملInteractive 3D Flow Visualization Using a Streamrunner
Flow visualization in 3D is challenging due to perceptual problems such as occlusion, lack of directional cues, lack of depth cues, and visual complexity. In this paper we present an interaction technique that addresses these special problems for 3D flow visualization. The feature we present, a streamrunner, gives the user interactive control over the evolution of streamlines from the time they...
متن کاملPearling: 3D interactive extraction of tubular structures from volumetric images
This paper presents Pearling, a novel three-dimensional approach to the interactive segmentation and modeling of tubular structures from a volumetric image. Given a user-supplied initialization, Pearling extracts runs of pearls (balls) from the image, where each pearl is specified by a center position and radius. The runs are combined into a graph, with bifurcations and possibly loops. By treat...
متن کاملSwifTree: Interactive Extraction of 3D Trees Supporting Gaming and Crowdsourcing
Analysis of vascular and airway trees of circulatory and respiratory systems is important for many clinical applications. Automatic segmentation of these tree-like structures from 3D data remains an open problem due to their complex branching patterns, geometrical diversity, and pathology. On the other hand, it is challenging to design intuitive interactive methods that are practical to use in ...
متن کاملFuzzy-connected 3D image segmentation at interactive speeds
Image segmentation techniques using fuzzy connectedness principles have shown their effectiveness in segmenting a variety of objects in several large applications in recent years. However, one problem with these algorithms has been their excessive computational requirements. In an attempt to substantially speed them up, in the present paper, we study systematically a host of 18 optimal graph se...
