6 Morphological Operations

Over view of Morphology

Morphology is the s tudy of the shape and form of objects. Morphological

image analysis can be used to perform

• Object extraction

• Image filtering operations, such as removal of small objects or noise from

an image

• Image segmentation operations, such as separating connected objects

• Measurement operations, such as texture analysis and shape description

VideoandImageProcessingBlockset contains blocks that perform

morphological o perations such as erosion, dilation, opening, and closing.

Often, you need to use a combination of these blocks to perform your

morpho logical image analysis. The e xamples in th is chapter sho w you how to

use blocks from the Morphological Operations library to count the number of

objectsinanimageandhowtocorrect for uneven illumination.

For more information, see “Morphological Operations” in the Image P rocessing

Toolbox documentation.
