Hippoc is a wonderful tool. I've run the engine on images that I have taken and had reviewed in detail by humans and compared that review to the results from Hippoc and not only does Hippoc provide a high level of fidelity to the reaction from people but it also provides detail that is harder for people to quantify and articulate. We might all know when an image 'looks right' but to put detail around that is not something that is easy to do. Hippoc can do that for you. Of course, I would expect that over time Hippoc will learn how to evaluate images that work because they are 'really out of left field' and this is something that I would imagine would be rather hard to teach a machine, so by adding your contribution to this effort you are helping to move us all closer to a point where we can get instant feedback.
