Hello.
We have received wrong results while using CrossCorrValid_Norm with IPP version 5.3 update 3.
The results are not always wrong, but for certain matrices (with certain size) , the results diviate for some points by 0.3. It doesn't matter what is the data in the matrix- Just the size. We have used previous versions of IPP and the results were always correct.
in ourtestings, this happens only while using UINT8 matrices(Images).
For Example: For two matrices: one sized 3X5 and a smaller one 2X3.
3X5:
85 194 177 253 39
241 233 2 32 19
23 250 93 243 132
2X3
149 84 17
2 227 19
IPP Result
0.121069 -0.616973 0.0344648
0.539306 -0.28021 0.162498
Ours and Matlab results
0.19392 -0.513159 0.0344648
0.578099 -0.178333 0.162498
As was said before , It does not matter what the data in the matrices is, the result always diviates.
Thank you
