I’m trying to optimize my naively implemented O(n^2) bilateral filter for 2D images. I googled and found a lot of theoretical explanations about the separate one. However, it seems there are things that should be taken special care of, regarding to the normalization.

I’m wondering if there are good references for especially the implementation?

  • $\begingroup$ Separable Bilateral Filter is quite simple to implement. Would you like a MATLAB code for that? $\endgroup$ – Royi Apr 6 at 18:48
  • $\begingroup$ Yes I'd like to see a matlab code. I actually think there should be only a simple two pass 1D convolution and no extra attention should be made... $\endgroup$ – jinglei Apr 6 at 22:38
