Resize input image (ID3D12Resource) to model size using directx

[bvnp43]

Hello,

I have a ID3D12Resource that contain input image, data is already on gpu. I need to be able to resize it to match the model fixed size, like 640x480. Then model's processing result need to be upscaled back. Is there any C/C++ code example where resize of the input/output resouce is implemented on directx? How this could be achieved without passing data to cpu, that obv would be a significant slowdown.

yolov4 sample has sample code here

DirectML/Samples/yolov4/yolov4.cpp

Line 647 in a2b2dd2

commandList->Dispatch(DivUp(m_origTextureWidth, 32), DivUp(m_origTextureHeight, 16), 1);

and around m_computePSO - it does exactly this, scales input image to dimensions the model expects.
