+This tool works on binary images, so other image types will automatically be converted to binary
+before they are analyzed.  This step is performed using the ImageJ2 **Make Binary** command with
+the following settings: **Iterations:** 1, **Count:** 1, **Pad edges when eroding:** No.  The tool
+allows you to choose the **Black background** setting.  If these settings are not appropriate,
+first manually convert the image to binary using the **Convert to binary (black and white) with ImageJ2**
+tool, which allows you to change them.
