Given the high resolution signal and the low pass filter (kaiser filter), is there a way to reconstruct the low resolution signal?
When we upsampling a discrete 1d signal by 2x, we first interleave the signal by 0, then pass through a low pass filter.
low resolution signal [x1, x2, x3, x4] -> interleave 0 -> [x1, 0, x2, 0, ...

What does 'downsampling' and 'upsampling' mean in coarse-to-fine segmentation?
The paper here in section 2.1 Coarse-to-fine prediction:
To increase the field of view presented to the CNN and reduce the
redundancy among neighboring voxels, each image is downsampled by a factor ...
