I could not find an image reduction function in IPP 3.0 for PCA.
I mean: a way to reduce images from a given size to another, smaller one, given a scale factor. For instance, with scale factor 2, a 128 x 128 image would be reduced to a 64 x 64 image.
It is strange, for that one seems to me a sufficient generic, simple and important function, a good candidate to be in a library of image processing functions.
I'd like to ask if there's such a function in IPP 4.0.
Thanks in advance for any help.
