in reply to BMP: Drawing or photograph?

I am not a computer vision expert. Here's how I would do it:

Load some representative target images into Mathematica or similar program and try out various filters. Start with transformations related to edge-detection or finding continous areas of colour and brightness. Visit http://mathematica.stackexchange.com/questions/tagged/image-processing if you need help.

When you have found a filter or combination of filters that correctly recognise to a high confidence whether an image is suitable for JPEG compression or not, recreate them in Perl. Binding to various imaging toolkits written in C are available, so this shouldn't be too complicated. The filter (pipeline) simply returns a boolean, use PNG or JPEG output format accordingly.

[ambrus]: GotToBTru: wait, you tell only the atom totals of what you want? Is that like ordering food in a restaurant by telling only the nutrient amounts you need, or
[ambrus]: like when a medieval scientist supposedly proves his priority inventing something by having previously published an anagram of a thousand letters long summary of the invention?
[choroba]: Progress! Nowadays, you can write a Perl script to generate such an anagram!
