Using the box filtering demo applet
Wait for the applet to load, completion is indicated by seeing a picture similar to one of those from the box filtering article. The 3x3 matrix represent the filtering kernel and has a default setting of no-filtering - everything else is zero except the one in the center. Try clicking on the matrix and change some values using that keyboard, you should be able to see immediate effect of any changes. Negative number is acceptable. Use delete or backspace key to reset a number back to zero.
