OpenCV image scaling is relatively slow. It seems, though I may be wrong, that the DPU is the perfect architecture to perform image scaling. I was wondering if it is actually possible to perform arbitrary image scaling on the DPU, and whether plans exist to implement this feature in a future release of DNNDK.
Thanks in advance,

Thank you very much for your reply. It turned out videoconvert was the worst bottleneck in my design.
I have already slightly reduced this bottleneck, by integrating the uyvy to bgr color space conversion in my GStreamer plugin. I could further reduce the bottleneck by using xfOpenCV. However, I wonder, am I incorrect to assume that both these color space conversions and arbitrary resizing of input images could be performed on the DPU? I would prefer it if I did not have to add extra firmware to perform a computation that can already be performed very well by the the DPU SoC platform.
