Hi, just a quick thought: difference comparision to 3d-unet? #199

I just wonder, all these nets, like what we have in 2d tasks: yolo, faster, cascade, they could by summarized as one-stage or two-stage. When it comes to 3d, U-net is now also available to 3d data, so except that U-net more often used to work with medical data, what else (and why) that are different? in design ideas or senses of intuition?
