src: 8-bit, single-channel (binary) source image. dst: Output image with calculated distances. It is a 8-bit or 32-bit floating-point, single-channel image of the same size as src. What are the trade-offs for using VPP vs. IPP for RGB to NV12 color conversion? I am currently using IPP but am unsure what the implication would be for switching to VPP. Is VPP a GPU implementation of color conversion on the GPU's EUs? From the VPP tutorial sample #6, it seems that VPP can save me...
