Hi François Yes, you may rely on Cython, so no need to code a pure Python version. Renaming the function as suggested would break backward compatibility, so I suggest adding hough_line as an alias, and deprecating hough over two releases.

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?
