why ippiMatchTemplateGetBufSize return 0 ?

l_luo — Sat, 05 Mar 2005 04:13:51 GMT

Could anyone point out whatgoes wrong with the following code?

the returned status indicates no error, butbuffsize is already 0. I wonder if there is restriction on the roi sizes.

int buffsize;

IppStatus

status = cv.ippiMatchTemplateGetBufSize_SqDiff(new IppiSize(128, 128), new IppiSize(32, 32), IppDataType.ipp8u, &buffsize);

Thanks!!

Hi,

it is expected behaviuor. The previous implementation of MatchTemplate function required some buffer, but in current version it is not necessary, so function returns 0 - means you need buffer with size 0 (in other words, you do not need buffer).
