IMAGING GLOSSARY

Morphology (image processing)

A neighborhood image-processing algorithm similar to image convolution except that Boolean logic is applied instead of arithmetic.

There are two types of morphology, binary and gray-scale. Both have similar operation but are carried out differently because of the data width.

The four major operations are: Erode - a filter that makes bright objects smaller. Dilation - a filter that makes bright objects larger. Opening - erosion followed by dilation. Closing - dilation followed by erosion. Do not confuse with morphing.
