napari-skimage-regionprops
A regionprops table widget plugin for napari
A napari plugin for measuring properties of labeled objects based on scikit-image
Usage¶
From the menu Tools > Measurement > Regionprops (nsr)
you can open a dialog where you can choose an intensity image, a corresponding label image and the features you want to measure:
If you want to interface with the labels and see which table row corresponds to which labeled object, use the label picker and
activate the show selected
checkbox.
If you closed a table and want to reopen it, you can use the menu Tools > Measurements > Show table (nsr)
to reopen it.
You just need to select the labels layer the properties are associated with.
For visualizing measurements with different grey values, as parametric images, you can double-click table headers.
Usage, programmatically¶
You can also control the tables programmatically. See this example notebook for details.
