A9 - Morphological Operation

Today, we'll all talk about shapes... shapes... shapes...

When I hear the word morphology, the first thing that comes to my mind is the biological context related to the study of structures and forms of plants and animals. Basically, this instinctive definition of mine can be stretched out to the image processing context. Practically, it means the same thing but instead of organisms, we talk about anything with no life like shapes.

Moving one step forward, morphological operations are then operations on an image that transform it to another for further processing and information extraction. These operations apply a structuring element (sort of a basis image) to an input image, creating an output image of the same size as the structuring element.

The most common type of morphological operations are dilation and erosion.
