About the method of upsampling

[qtz980805]

Thanks for your significiant work. I would like to ask the method of upsampling the depth hypotheses. Is it the nearest interpolation or the bilinear interpolation? I think both of them would influence the accuarcy, especially in edge regions.
Look forward for your reply!

Hi, among the different scales, we directly upsample the depth map of the previous scale and then recompute which bin each depth is in. When upsampling the depth maps, we use bilinear interpolation.
