IppFilter usage

[shyweissman]

I am using the following filter : 0 0-2 0 0

0 0 10 0

-21 6 1 -2

0 0 1 0 0

0 0 -2 0 0

it is writen in code ifresult > 255 result = 255

ifresult < 0 result = 0.

I am looking for a way to use ippfilter or any other ipp routine to speed it up.

Any Suggestion?

Thanks.

Hi,

There is no special function for such kernel. The possible way is to use therow filter for kernel {-2 1 6 1 -2} and the column filter for kernel { -2 1 0 1 -2} (see separable IPP filters0 and add their outputs. To enhance performance it may be organized as a pipiline.
