Knife-edge scanning microscopy for connectomics research

TL;DR: Kniss-Edge Scanning Microscopy (KESM) as discussed by the authors has been successfully used to scan whole mouse brains stained in Golgi (neuronal morphology), Nissl (somata), and India ink (vasculature), providing unprecedented insights into the systemlevel architectural layout of microstructures within the mouse brain.
Journal ArticleDOI

Specimen preparation, imaging, and analysis protocols for knife-edge scanning microscopy.

TL;DR: The pipeline, including specimen preparation (fixing, staining, and embedding), KESM configuration and setup, sectioning and imaging with the KESS, image processing, data preparation, and data visualization and analysis are described, with the emphasis on specimen preparation and visualization/analysis of obtained KESm data.
Journal ArticleDOI

Statistical geometric computation on tolerances for dimensioning

TL;DR: A new geometric model for representing statistically-based tolerance regions by utilizing generalizing root sum square methods for compositing and cascading over tolerance zones is presented and a generalized RSS method is proposed for modeling geometric representations of tolerances in the statistical way.
Journal ArticleDOI

Hardware Accelerated Segmentation of Complex Volumetric Filament Networks

TL;DR: A novel method to trace filaments through scalar volume data sets that is robust to both noisy and undersampled data is described, and graphics hardware is used to accelerate the tracing algorithm, making it more useful for large data sets.
Proceedings Article

2009 SIAM/ACM Joint Conference on Geometric and Physical Modeling

TL;DR: The 2009 SIAM/ACM Joint Conference on Geometric and Physical Modeling as mentioned in this paper was held in San Francisco, from October 5 to October 8, 2009, and attracted high-quality, original research contributions that strive to advance all sorts of aspects of geometric and physical modeling, and their application in design, analysis and manufacturing, as well as in biomedical, geophysical, digital entertainment, and other areas.
