fluorender 2 20We are excited to announce the latest release of FluoRender, version 2.20, which incorporates improvements, bug fixes, and new features.

New Features:

  • Clustering algorithms. Three clustering algorithms for segmentation are added: expectation-maximization on Gaussian mixture, DBSCAN, and k-means. Users can use these methods in the "Component" window.
  • Improved tracking algorithms. Tracking accuracy has been improved. We improved the algorithm for generating the track map and incorporated clustering algorithms to automatically segment during tracking. Users can also adjust a series of parameters in the "Tracking" window to fine tune the tracking.
  • A new 4D script for tracking sparse particles. The 4D script allows users to track selected features in a time sequence. No initial segmentation is required for it to work. It can be used to track sparse and small features conveniently.
  • A density setting for component generation. The density setting has been added in the basic component generation. Its concept is based on the clustering algorithm DBSCAN. However, its implementation is based on the synthetic brainbows algorithm, which uses GPU to compute segmentation of dense data sets.
  • Render view output enlargement. The option has been added when the render view is captured and saved as an image. Users can set an output image size larger than the render view size.
  • 4D script list. The list of built-in 4D scripts has been added to the "Record/Export" panel. Users can easily select and switch 4D scripts without browsing to the actual files.

In this release, we mainly improved the usability of a series of functions for 4D analysis, including the component analyzer, 4D scripts, paint brush tools, and format supports. We have also made a series of video tutorials and published them on YouTube.
scirun5The Scientific Computing and Imaging Institute is excited to announce the first official alpha release of SCIRun 5.0!

New features include a new user interface based on the cross-platform Qt toolkit, updated graphics and visualization system, improved algorithm stability, expanded test coverage, a leaner and modernized codebase, better math library support through Eigen, and streamlined support for new modules and toolkit development. A Python scripting engine and Matlab interface will be available in our beta release.
