Edge Detection Filters

Use edge detection filters to highlight the edges of objects. Edge detection filters, however, often increase the noise in an image, too. Therefore, it's often better to smooth an image, before you apply an edge filter. How you perform several image processing operations immediately one after the other, you will find described here.

In the Process > Edge Detection Filters menu, you will find the following filters:

Sobel

Roberts
