Hi,

I have written the hough transform for circles in python and have a good basis for peak detection.

I have few questions:
1/ in skimage/transform/hough_transform.py
Cython version of hough() is imported like this (below the python version)
59 # try to import and use the faster Cython version if it exists
60 try:
61 from ._hough_transform import _hough
62 except ImportError:
63 pass

Should I do the same for hough_circle()? or just implement the cython version?
I don't see why cython would not be available...

2/ For disambiguation, I suggest to rename hough to hough_line(). The same for peak detection.
Any comment on that?

Cheers,
François.
