AI is coming: a short story of emotion recognition starring Game of Thrones Tooploox

How difficult can it be to detect rectangles on an image? Well… it can be nearly impossible if there are no actual rectangles at all. Edges between a YouTube video's background and overlaid GoT scenes are visible only due to the optical illusion called illusory contours. In this task, we had to rely a little bit on the incredible vision of humans and make some annotations. Thankfully, it was enough to manually mark coordinates only on a single frame per YouTube video.
