What would be very interesting would be some sort of 'vgrep' that would
let you find images similar to a known sample.

This way you could, say, screenshot the image, then search your browser
cache for the similar source file, based on edge detection or similar.

Not something I'd use every day, but could be useful on the odd
occasion.  Anyone familiar with the field at all?
