Is there any float type IMAGE SAMPLING function ?

Hi !

I've found only 8u type sampling function under JPEG function in IPP ?

Is there any float typeIMAGE SAMPLING function ?

Thanks

Jack

Hi Jack,

The functions you can see in ippJP library are JPEG/JPEG2000 specific. For general image processing functions you should take a look on ippIP library. I believe ippiResize function can fit your needs, it supports 8u, 16u and 32f data types.

Vladimir

Hi again !

Thanks for your prompt reply . ippiResize is comparetevely slowagainst sampling function ( by factor 3 or 5 ) and uses averaging algorothm , I'd like to find sampling function for image processing like it exists for signal processing , but imageoriented .

Thanks

Hi,

we do not have such functions for images. But you can use existing 1D functions (from ippSP) on row by row basis. What do you think?

Hi again !

Thanks for your reply . It could be useful , but now there is a question of performance and if is it any advantage agaist regular C code . Should be checked.

Thanks

Jack

Right, I hope performance will be good enough. Please report ifyou findsome problems with that.
