Hello all,
these days I was reading some scientific articles dealing with photographic image aesthetics.
The idea behind is to develop software which will automatically divide images into two groups - good and bad.
All researchers are aware that this is extremely hard task, unsolvable at the moment.
Their test and train database usually consist of 10% of best and 10% of worst images downloaded from some
photo comunity site (for example 60000 images in total, for research they take 6000 best and 6000 worst
photos).
If they tend to make usable software, usable for an average user,what kind of database they should develop?
Maybe regarding some features this 6000 best images may be representative (color, contrast, sharpnes...), but
regarding some other features may not. For example - composition. An average user will follow (more or
less) rule of thirds, golden rule etc. and will rarely make good photos breaking these rules. Pro user will break
it more often making extraordinary photos.
My question IS what do you think about the before mentioned selection of images for the database (10%
of best and 10% of worst images)?! Is this selection representative or not?
It is clear so far that at the moment computer vision can not accomplish such tasks.
Regards, Matija.

I think it's ridiculous to allow computer software determine what constitutes a "good" or "bad" image. What one person may find as "good" another may find "bad" and vice versa. I don't think it would be representative of anything but computer generated statistics.

Art is interpretative. It's that simple.

Computer A could prefer IreneM type photos,
Computer B could prefer Posthumous type photos,
Computer X could prefer trolling the forums.

Well, starting with the "best of the best" and "worst of the worst" would certainly seem to be an option... as would be looking at correlation between certain characteristics across the entire spectrum of images. The problem of curse is how images are rated. Who really determines where an image lies in the spectrum of extremely good to really bad?
My personal view is that the endeavor you propose may have some use in guiding users with very limited knowledge and experience, but that "good" photography is as much about the viewer's reaction to a photo as it is about the actual content and technical merit of the photo. As such, the value of an image rating tool will be limited to technical merit only.
