Morphological Operations
Function: Performs morphological operations on the input image, including dilation, erosion, opening (erosion followed by dilation), closing (dilation followed by erosion); gradient operation (difference between dilation and erosion); top hat operation (difference between original image and its opening, used to separate lines or noise brighter than adjacent areas); black hat operation (difference between closing of the image and original image, used to extract small dark objects in bright backgrounds); hit-miss (intersection of foreground and background erosion operations, can achieve object thinning and pruning, often used for object recognition, image thinning). Only grayscale input is supported for hit-miss transform.
Input Parameters:
| Name | Type | Valid Range | Default Value | Meaning |
|---|---|---|---|---|

The input can be a color graph or a grayscale graph. This method handles many pairs of binarized graphs. Hit - Transform method not hit Only grayscale graphs are supported. |
