A semi-automatic surface reconstruction framework based on T-Surfaces and isosurface extraction methods

E. Strauss, W. Jimenez, G. Giraldi, R. Silva, A.A.F. Oliveira
Proceedings. XV Brazilian Symposium on Computer Graphics and Image Processing  
In this paper we present a new approach which integrates the T-Surfaces model and isosurface generation methods in a general framework for surface reconstruction in 3D medical images.  ...  T-Surfaces is a deformable model based on a triangulation of the image domain, a discrete surface model and an image threshold.  ...  Based on these elements (discrete surface model, simplicial decomposition framework and threshold) we propose in this paper a semi-automatic segmentation approach for ¦ § medical images based on isosurface  ...

Advanced interactive medical visualization on the GPU

Natalya Tatarchuk, Jeremy Shopf, Christopher DeCoro
2008 Journal of Parallel and Distributed Computing  
Our method combines direct volume rendering via ray-casting with a novel approach for isosurface extraction and re-use directly on graphics processing units (GPUs) in a single framework.  ...  The resulting polygonal surface can also be analyzed for geometric properties, such as feature area, volume and size deviation, which is crucial for semi-automatic tumor analysis as used, for example,  ...  Acknowledgments We thank Daniel Szecket for his work on the user interface used for our system.  ...

2005 Computer Animation and Virtual Worlds  
In this paper, we propose a novel practical method for blob-based liquid 3D morphing. Firstly, blobby objects are employed to approximate a given polygonal surface.  ...  The primitives in the medial axis sphere-tree of a polygonal model are utilized as initial blobsthis greatly improves the robustness and efficiency of the blob-based approximation.  ...  In our future work, anisotropic primitives, for example ellipsoids, will be considered to achieve a better approximation on the region with fine-scale features.  ...

Interactive Exploration of Remote Isosurfaces with Point-Based Non-Photorealistic Rendering

Guangfeng Ji, Han-Wei Shen, Jinzhu Gao
2008 2008 IEEE Pacific Visualization Symposium  
Instead of relying on the conventional smooth shading technique to render the isosurfaces, a point-based technique is used to represent and render the isosurfaces in a remote client-server environment.  ...  The non-photorealistic nature of the proposed rendering method enables the server to transmit only the essential surface features, which substantially reduces the network traffic.  ...  A NPR technique is used by the client to reconstruct and render the surface, and generate images resembling point stippling.  ...
