How can create the fuzzy object?

I have a binary image, I would like to make the border of shapes fuzzy. How can I make it fuzzy?

wouldn't you have to convert to grey scale?

Depends what they mean by "fuzzy". For example, if you were to find the border pixels, and all along the border randomly set or clear some fraction of the border or neighboring pixels, then the resulting image would be "fuzzy".
