Hello,
To infer my DNN models in driveworks api the input should be CHW as I understand. When I read a frame from camera, what is its layout CHW or HWC? If its not CHW how can i convert it?
I looked from official examples but quite didn’t understand it clearly.

Dear @kaltinok ,
Could you check dwImageProperties → DwImageFormat for input image? Have you checked our DNN samples?
Could you check file:///usr/local/driveworks-2.2-old/doc/nvsdk_html/image_mainsection.html and dwImage_copyConvert() function and see if it helps?
