This repostitory is a merge of the old LinearDistance and PointAnalysis Repos.

• ImageJ (tested with ImageJ 1.50e)

Copy the File MSTB_.jar in the plugins/jars folder. When using Fiji, you can simply add the update site SimonKlein.

Plugin for ImageJ to measure linear distances in images in X and Y direction. At this time, two methods are implemented: First, the automatic scan of a binarized, two phased image. Second, the interactive placement of marks which will be measured afterwards (Linear Interception).

Measure linear distances (two phases, 8 bit): Used for the calculation of mean free paths in a two phase material. Measure linear distances (single phase, interactive): Used for the measurement of grain size in single phase metal.

Open one or more binary (black/white) images or binarize an image. Start the plugin by selecting "Plugins>Analyze>Measure linear distances (two phases, 8 bit)" and select the results you want to obtain.

Available Options:

Open any kind of image. Start the plugin by selecting "Plugins>Analyze>Measure linear distances (single phase, interactive)". Set the distance and offset you prefer in either pixels or units (if calibrated). Set marks in the image by left click, remove marks with right click. When done, press OK at the bottom of the image and select the results you want to obtain. The selected statistics for the stripe-length between marks will be presented afterwards.

Plugin for ImageJ to measure domains (e.g. phases) in images using a grid of points.

Plugins -> Analyze -> Point Analysis (multiple domains)

Open one image. Start the plugin by selecting "Plugins>Analyze>Point Analysis (multiple domains)" and enter the number of domains you want to measure and the number of points to seed. Optionally, the points can be placed randomly instead of a grid.

Now you can try to automatically assign the points by entering a threshold between 0 and 255 and a porperty to match (H=Hue, S=Saturation, B=Brightness). This maybe only useful for two domains. By clicking single points, you can change the assigned domain (left=circle, right=reverse). When clicking OK, the number of points for each domain is printed.
