Image Processing Examples Of Resulting Images After Some Common Morphological Operations Dilate The Dilate operation sets each pixel in the output image as the largest luminance value of all the input image pixels in the neighborhood defined by the selected kernel size. (Currently fixed to 3x3) Erode The Erode operation sets each pixel in the output image as the smallest luminance value of all the input image pixels in the neighborhood defined by the selected kernel size. (Fixed to 3x3) Close The Close operation is equivalent to a Dilate operation followed by an Erode operation. This has the effect of removing small dark particles and holes within objects.
Open The Open operation is equivalent to an Erode operation followed by a Dilate operation. This has the effect of removing peaks from an image, leaving only the image background. Histogram Operations The action of a histogram operation depends on the histogram of the Input Image. The Image Processing Tool provides the following histogram operations, each of which can only be ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 520
