Hi, Hi, I'm running OpenCV's bilateralFilter on an ARM quad core mobile device. I have the following questions:

  1. I pass 5 as the d parameter. The filter on H and W is actuall from -2 to 2, right?
  2. As far as I can see the code ends up in the BilateralFilter_8u_Invoker (this is a CV_8UC3 input matrix). How many CPU threads/cores are used in that case?
  3. It seems that on intel arch the code uses SSE. Does ARM implementation have neon support? where can I see that in the opencv code?

thanks.
