Best way to extract smaller image patches(3D)?
First step, I would like to read 10 three-dimentional data with size of (H, W, S) and then downsample these data to (H/2, W/2, S/2).
Second step, I want to design a sliding window to extract patches with size of (64, 64, 64) from the above images.
Are there some examples about this processing in Dataloader?
