Is it possible to use non square images ? #1

Hi, thank you so much for the nice work! It seems that it is only possible to use square images in your code, why?

Hi, yes that's true, that's how it is implemented for now. That's because I mostly used TV for CT reconstruction for which images are typically square, see https://github.com/eboigne/PyRAMID-CT.

I don't really plan to update the code for non-square images right now. But, as a quick work-around, I'd recommend filling in your images with zeros into square images. You'll loose some performance, but that should be reasonable if your images are close to square.
