SubPixel Convolution Upgrade #457

Open danieltudosiu opened 4 years ago

danieltudosiu commented 4 years ago

This issue was sparked by the implementation of SubPixel Convolution that is available in Fast.ai [1]

Things to do:

[1] PixelShuffle ICNR [2] Checkerboard artifact free sub-pixel convolution [3] Checkerboard artifacts free convolutional neural networks

danieltudosiu commented 4 years ago

A new partial limitation has been created by this extension. If ICNR initialization is used then the upsample factor MUST be an integer.

Did the modification on the brach with the same number as the issue, waiting for the person that implemented ICNR to validate my generalization.
