Hi,
IPP has functions ippiFilterRow and ippiFilterColumn for applying seperable 1-dimensional filters to an image.
I had hoped that the in-place versions of these functions would implement a recursive filter, ie: y = k1y[i-1] + k2y[i-2] + ... which updates y after computation and uses that as the next value for (what will become) y[i-1]. My initial tests seem to indicate that this is not the case. Is this expected? If it is expected, is there functionality available in IPP for recursive 1-dimensional filters (going in both the forwards and backwards directions)?
Thanks

Hello,
It is true that filter are not the repeat ones. Do you want to filter data on each line and each column? You may try the one dimensional filter function here:
