how to resize a sliced image

I'd like to resize a very big image. I want to partition it to multiple slices and resize them using different threads. What I am concerned is that how to deal with interpolation around their boundaries. If I use IPP resize function to process each slice, I think symmetric extension will be used, which I want to avoid because the pixels outside a slice do exist in the next one. I am afraid the symmetric extension will result in some visual distortion between these slices.

I found a new function ippiResizeShift in IPP, but have no idea about how to use it. Can you give me some clue? Thanks.

Hello,

I would recommend you to take a look on IPP image processing samples, specifically image-tiling sample, which demostrate how to build tiled processing for blur, rotation, xor and resize.

Regards,
Vladimir
