Does unpatchify perform averaging ? #9

Closed omagdy closed 3 years ago

omagdy commented 3 years ago

So I am doing some image processing on 3D images and rather than operate on the entire image I want to split it first into patches and perform the image processing on each patch.

Say I have an image with dimensions 240x240x160 and I patchify it with a patch shape 40x40x40 and 20 as step size then the patches will be overlapping.

My question is the following: When these overlapping patches are unpatchified, are the overlapping pixels averaged over all their values to get the final output ?

Thanks in advance.

No, there's no averaging for overlapping edges of the patches. The overlapped edges will be cropped away.

Any plan to add the function for averaging for overlapping edges of the patches? Thanks!

@yongshuo-Z https://github.com/dovahcrow/patchify.py/issues/6 I was planning to let this library support recovering from overlapped edges but haven't got time to implement it.
