particle analyzer etc.

[Matthias Kirsch]

Dear all,

is there a way to select particles based on parameters other than area or circularity, e.g. mean density in an image, the measurements are redirected to, and to combine such parameters logically, such that only particles are measured, which are of a certain size and mean density...
In addition: is there some way to sort a results table easily, like in EXCEL and then click on a specific particle in the table and get this particle highlighted in the image and vice versa.

Thanks very much

Matthias

Hi Matthias,

The ShapeLogic plugin has a Color Particle Analyzer, in which you can
make rules based on different properties. Here is a rule for a
labeling particles that have an aspect ratio between 0.9 and 1.1 and a
gray value of over 150.

LoadLetterStreams.rule("Light round", StreamNames.COLOR_GRAY, ">", 150, null);
LoadLetterStreams.rule("Light round", ASPECT_RATIO, "<", 1.1, null);
LoadLetterStreams.rule("Light round", ASPECT_RATIO, ">", 0.9, null);

The selected particles can be exported to Excel, but not highlighted
in the images.
