It may not add totally new information, but it does more than create an image that looks nicer. It's not just inventing plausible information, it's providing the most likely new information given the available data. For example, "given what we can see of that eye chart, it's most likely the little blob is a 'G'". So it's adding new interpretive statistical information, which could be pretty helpful in some situations.
- ef4 14y agoThe problem is that the algorithm is using a definition of "most likely" that doesn't help you answer questions about the real scene captured in the image. For example, if what you're really trying to do is decode text, this algorithm will lose every time to one that knows the prior probabilities of natural human languages. ("ONLY" is much more probable than "QNLY", but this algorithm does't know that).
- ansgri 14y agoIt doesn't add any information to a human eye, but may be very useful preprocessing for algorithms that do not know about the quasi-fractal structure of natural images, and that's most of CV.
