speed boost with gpu

[enymfc25173]

It works very well!
But the speed is slow comparatively. Is it possible to boost the speed by gpu or other ways?

Hi @enymfc25173, I think there are two ways to speed up:

1. Reduce the image size before perform skew estimation, the DFT takes a lot of time for large image. (Can have a look here https://github.com/phamquiluan/jdeskew/blob/master/jdeskew/estimator.py#L16)

2. As you said, if s.o. can bring this function to GPU (https://github.com/phamquiluan/jdeskew/blob/master/jdeskew/estimator.py#L76), I think the algorithm will be speed up. It's feasible.
