That also demonstrates the difference between having the possibility to optimize input until the output matches the known values and having to process "real life" images made under different conditions.
The later is certainly more interesting: e.g. I dream of having an OCR that is "always right" no matter how bad the image is.
Controlled lighting is extremely helpful in computer vision and key to the operation of a lot of industrial uses of it. From a system design point of view it makes a lot of sense, but obviously it's not possible in many applications (and researchers obviously want to go after the toughest problems, and would rather mostly solve a hard problem than entirely solve an easier one).
