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
