* Erode an image using grayscale morphology. Erode takes the
* minimum of all the pixels identified by the structuring element.
*
* The structuring element is assumed to be composed of binary
* values (zero or one). Only elements of the structuring element
* having values > 0 are candidates for affecting the center pixel.
