Hi,

I'm not quite understand your question. Are you asking about some features of IPP function which might be missed?

okies .. here it goes ..
i am trying to use the following functions ..

ippiFilter_8u_C1R
The destination is filled with all ZEROS if the height of the kernel matrix is EVEN i.e. functions fails for masksizes 1x2 or 2x2 or 4x4 or 3x4 or 3x2

ippiFilterBox_8u_C1R
The destination is filled with all ZEROS if the height or width is equal to ONE i.e. function fails for all mx1 or 1xn masksizes


ippiFilterMedian_8u_C1R
The destination is filled with all ZEROS if the mask size is not odd square, ex. it works only for sizes 1x1 or 3x3 or 5x5

Hi,

The mask size must be odd but it is not required to be square. The mask sizes are legal:

1x1 1x3 1x5 ,,, 1x(2n-1)
3x1 3x3 3x5 3x(2n-1)

(2m-1)x1 (2m-1)x3 (2m-1)x5 (2m-1)x(2n-1)

n and m are natural numbers.

is that restriction of being odd only for FilterMedian or any filter that uses "IppiSize maskSize"

thank you.

This restriction is for FilterMedian only. You can find the mask size restrictions description for every particular filter in the manual. For example the general ippiFilter works with an arbitrary mask size.
