Skeleton Dark

Use this filter to calculate the skeleton of dark object's in the image. If the objects are bright, the skeleton for the background is calculated. You can find the Skeleton Dark filter in the Process > Morphological Filter menu.

Before using the filter

This filter can only be applied to binary images. Therefore, you have to first binarize the image by using the Image > Mode > Binary... command. Otherwise, in the menu for morphological filters, the Skeleton Dark command is grayed out. You can find more information on binarizing here.
