I can't say for sure whether dft() is entirely thread-safe, but it does look like you can call dft() in a tbb::parallel_for loop. I had some caching issues buried elsewhere in my code that were leading to the NaN's being introduced in the multi-threaded case. |

Hi, I'm having some issues with dft() giving back arrays filled with NaN when called in a multi-threaded environment (tbb::parallel_for). The same code produces valid results when called in a sequential for loop. I know FFTW is not thread-safe, is OpenCV's DFT also not thread-safe? Thanks, Phil |
