Image Processing Toolbox

Example: Marker-Controlled Watershed Segmentation

This example illustrates how to use many different morphology functions in combination to accomplish an image processing task: segmentation. In segmentation, objects in an image that are touching each other are divided into separate objects. (To see other extended examples, view the Image Processing Toolbox Morphology demos.)

The example performs these steps:

• Step 1: Read in Images
• Step 2: Create the Structuring Element
• Step 3: Enhance the Image Contrast
• Step 4: Exaggerate the Gaps Between Objects
• Step 5: Convert Objects of Interest
• Step 6: Detect Intensity Valleys
• Step 7: Watershed Segmentation
• Step 8: Extract Features from Label Matrix
