This works pretty well for me.

infile = '~/Pictures/dave_index.jpg'
READ_JPEG, infile, image
TV, image, TRUE = 1
cr = ''
READ, cr, PROMPT = 'Enter <cr> to continue ...'
image = SMOOTH(image, [1, 20, 20], /EDGE)
TV, image, TRUE = 1

The picture is from http://www.dfanning.com/images/dave_index.jpg.

After smoothing, Dave looks much like he did at the end of the last
Expert Programmers Association meeting.
