Ah I see, somehow I overlooked that one. Don't mind me then. Anyway, here's a comparison of the number of operations between the generic algorithm and this one per output pixel for the Lena image. Actually the mean number of comparisons between the two is rather close. |

Use a minimum number of comparisons for obtaining the median of a 9 element vector instead of the generic p_median_f32 function, as all medians calculated in the p_median3x3 filter are of length 9.
