Proper way to have multiple ImageManip nodes

Rezahojjatysaeedy

Hi,

I have multiple NN in my pipeline. For one of them I'm using cam.setPreviewSize(300, 300) and then linking it with ImageManip node as shown in examples. But I also have another NN that accept different size of images, say 512x512. I wonder what's the most efficient way to provide input frames for this second NN. Should I create a second ImageManip node. If So, what Should I link to it? cam.preview that I previously resized to 300x300 or cam.video which is the 1080P output of the camera?

Hi Rezahojjatysaeedy
Why are you linking preview size with a manip? I'd have preview linked to one NN, and the rest from .video->manip->NN. This is because preview output is a bit more efficient (i believe).

Thanks,

Thanks @Jackmarks ,

You're right. This works better.
