For erosion, we use the formula

E(x,y) = Minimum{A(x – i, y – j ) x B(i , j)}

$\hspace{30mm}$ 0 ≤ i ≤ m - 1

$\hspace{30mm}$ 0 ≤ j ≤ n - 1

Here we multiply the mask coefficients with the image values and choose the minimum value.

We place this minimum value at the position of the origin of the structuring element.
