template<class T >
void vil_greyscale_erode ( const vil_image_view< T > &  src_image,
vil_image_view< T > &  dest_image,
const vil_structuring_element element 
)

Erodes src_image to produce dest_image (assumed single plane).

dest_image(i0,j0) is the minimum value of the pixels under the structuring element when it is centred on src_image(i0,j0)

dest_image(i0,j0) is the maximum value of the pixels under the structuring element when it is centred on src_image(i0,j0)
