FIGURE 9.5: An example of grayscale erosion. In grayscale dilation, bright pixels increase or grow and dark pixels decrease or shrink. The effect of dilation can be clearly observed in a region(s) where there is a change in the grayscale intensity. Similar to binary dilation, grayscale dilation fills holes.

The following is the Python function for grayscale dilation.

scipy.ndimage.morphology.grey_dilation(input, footprint) Necessary arguments: input has to be an ndarray. Optional arguments: footprint is a structure element that is an ndarray of integers. Returns: An ndarray.
