Description

This plugin provides the possibility to filter segmentation objects by measurements (shape and intensity). E.g. you segmented your cells, and you want to exclude segmentation objects that have a mean intensity below a certain value.

It is intended for 2D and 3D images.

You can interactively set minimum and maximum thresholds on measurement properties, and napari will show a preview of the selection.

Measurements are based on scikit-image regionprops. However, not all properties are implemented, and they are more restricted for 3D images.

Usage: Quick start

1. Start napari
2. Start the plugin from the menu: Plugins > Filter labels by properties
3. Add a label image
4. (optionally) Add a corresponding intensity image with the same (Z)YX shape
5. In the widget, select the property you want to filter on
6. Adjust the min/max sliders
7. When you are ready to create a new label layer click the Create labels button in the widget
   • depending on the number of labels and image size, this may take longer -> check the napari activity

Usage notes:

When dealing with more than 100 label objects in an image, the filtering view update is triggered only once you release the sliders.
