README

        
Recursive bilateral filtering (developed by Qingxiong Yang) is pretty fast compared with most edge-preserving filtering methods

- computational complexity is linear in both input size and dimensionality:

- takes about 43 ms to process a one megapixel color image (i7 1.8GHz & 4GB mem)

- about 18x faster than *Fast high-dimensional filtering using the permutohedral lattice*

- about 86x faster than *Gaussian kd-trees for fast high-dimensional filtering*
