Re: total variation denoising

have you been able to do some benchmarks to see if the performance hit from Python is reasonnable?

I had done a rapid benchmark when I translated the C code into Python, and found that the Python code was 3 times slower compared to the C with Cython wrapping. But now I have improved the performance with a stop criterion on the energy, instead of a fixed number of iterations; hence it is difficult to compare now (of course, the stop criterion could be implemented in C too, but I was much more comfortable to do it in Python!). The performance has to be reasonable, because I have a student who is using this code to denoise large 3D images (512^3)! Emmanuelle �
