resizing an image by duplicating pixels

Amichai_G_ — Wed, 27 Jan 2016 12:01:28 GMT

I want to resize an image in a particular way that duplicates a pixel vertically and horizontally. For example

source image destination image

1 2 1 1 2 2

3 4 1 1 2 2

3 3 4 4

Is there an IPP function that can do this?

Thanks

How about to use ippiResizeNearest with NN interpolation directly?

Changes an image size using the nearest neighbor
interpolation method.
12 Intel® Integrated Performance Primitives Reference Manual, Volume 2: Image and Video Processing

IppStatus ippiResizeNearest_<mod>(const Ipp<datatype>* pSrc, Ipp32s srcStep,
Ipp<datatype>* pDst, Ipp32s dstStep, IppiPoint dstOffset, IppiSize dstSize, const
IppiResizeSpec_32f* pSpec, Ipp8u* pBuffer);

and you can find ipp resize sample in IPP install folder..

Best Regards,
