Description
The Erosion block slides a neighborhood or structuring element over an image, finds the local minima, and creates an output matrix from these minimum values. If the neighborhood or structuring element has a center element, the block places the minima there, as shown in this figure.
If the neighborhood or structuring element does not have an exact center, the block has a bias toward the upper-left of the central elements and places the minima there, as shown in this figure.
This block uses flat structuring elements only.
