Minimum filter is a non-linear filter which works in the following way: for each pixel it searches pixel with minimum brightness in "running window" of the radius specified with Radius property. This pixel is copied to the result bitmap.
That's why if you apply this filter on the image with has black objects on white background (for example text), they will be dilated.
