While the details of DeepFocus are technical enough to be of interest only to developers, the upshot is that Oculus’ software uses AI to create a “defocus effect,” making one part of an image appear much sharper than the rest. The company says the effect is necessary to enable all-day immersion in VR, as selective focusing reduces unnecessary eye strain and visual fatigue.
“With deep learning, our system was able to grasp complex effects and relations, such as foreground and background defocusing,” explained Oculus research scientist Anton Kaplanyan, “as well as correct blur at occlusion boundaries. And by generating a rich database of ground truth examples, we were able to cover a much wider range of defocus effects and set a new bar for depth-of-field synthesis.”
