Binary Image Filtering—Erode, Dilate, Open, Close Modules
The Erode, Dilate, Open, and Close modules all morphologically change the image.
The input image must be binary.
Tip: To create a binary image, call the Threshold module before calling a
morphological filtering module. Threshold produces binary output.
The morphological change modules are:
❑ Erode—Performs morphological erosion of the image. Erosion is the process of
turning off (setting to zero) pixels at the perimeter of a cluster of pixels, thus
reducing the size of each pixel cluster. This eliminates very small clusters and can
separate multiple clusters that are barely "touching."
