Hi,
These functions are used to upsample the chroma components of image. The difference is in storage format. fcvUpsampleVerticalu8 handles CrCb stored in planar format, while the other function expects CrCb to be interleaved.
Sorry for confusion. The documentation will be improved soon to remove such ambiguity.

Thank you! Am I need to pass only chroma components to this function or pass YCrCb data, and function automatic find and upsample chroma components?
Ok, understood. And what can resize Y component? I'm just want to upsample my RGB image (in c++ app). Firstly, I'm converting it to YCrCB, and then want to upsample.
The two functions of your concern are typically used to do YUV422 to YUV444 upsampling etc. where you don't need to do anything for Y component. I wonder whether upscaling is what you need. If that's the case please check out fcvScaleUp... functions.

Thanks, it was the problem.
