Synthetic aperture-like algorithms are also common at SIGGRAPH if you go through the past two decades. A quick search didn't unearth any, but there is open source software to do parallax depth inferencing, and you could just apply proportional gaussian blur kernels to each depth segment to get a very similar effect.
