Frequently Asked Questions

What are morphological operations?

Morphological operations process images based on shape. They apply a structuring element (kernel) to the input image to produce an output. Common operations include erosion (shrink), dilation (expand), opening (remove noise), and closing (fill gaps).

What is the difference between opening and closing?

Opening (erosion then dilation) removes small bright spots and thin connections. Closing (dilation then erosion) fills small dark holes and connects nearby objects.
