Morphology is the study 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
The Video and Image Processing Blockset software contains blocks that perform morphological operations such as erosion, dilation, opening, and closing. Often, you need to use a combination of these blocks to perform your morphological image analysis. Morphological image analysis can be used to perform image filtering, image segmentation, and measurement operations.
The examples in this chapter show you how to use blocks from the Morphological Operations library to count the number of objects in an image and how to correct for uneven illumination.
For more information, see Morphological Operations in the Image Processing Toolbox documentation.
