u-track is a multiple-particle tracking Matlab software that is designed to (1) track dense particle fields, (2) close gaps in particle trajectories resulting from detection failure, and (3) capture particle merging and splitting events resulting from occlusion or genuine aggregation and dissociation events. Its core is based on formulating correspondence problems as linear assignment problems and searching for a globally optimal solution.

Data can be read using bio-format and interfaced with OMero data base.

It comes as a standalone software, but can be used as a library, which is according to the authors the most widely used version of it.

• Version 2.2 adds parallel processing functionality for multi-movie datasets when using the GUI.
• Version 2.1 enables the analysis of movies stored on an OMERO server
• Version 2.0 includes two new tracking applications: microtubule plus-end tracking (previously distributed as plusTipTracker) and nuclei tracking
• A third optional processing step has been added to the analysis workflow, track analysis, with two methods: motion analysis and microtubule plus-end classification

For more information, please see Jaqaman et al., Nature Methods 5, pp. 695-702 (2008). Besides basic particle tracking, the software supports the features described in Applegate et al. J. Struct. Biol. 176(2):168-84. 2011 for tracking microtubule plus end markers; and in Ng et al. J. Cell Biol. 199(3):545-63. 2012 for tracking fluorescently-labeled cell nuclei.

Computes signed curvature along a line.

This plugin facilitates the assembly of a mosaic of overlapping individual images, or tiles. It provides a semi-automated solution where the initial rough positioning of the tiles must be performed by the user, and where the final delicate adjustments are performed by the plugin.

The MosaicJ plugin requires that a second plugin, named TurboReg, is installed. 

This plugin allows to analyze the local direction and frequency of sinusoidal waves, for example muscle repetitive stripy pattern.

The output are optionally smoothed lambda (inversely proportional to the frequency) and phi (direction in degrees).

This plugin creates a non-destructive grid of lines, crosses or points on the current image or stack. You can specify the grid type (lines, crosses or points), the area per point (in pixels or physical units), and the color.
