detector1 --> cropped images --> detector 2

Hi,

How to send dector 1 cropped image to dector 2. I tried by setting

operate-on-gie-id=1
operate-on-class-ids = 0

but detector 2 works without cropped image from detector1. It mean detector 2 is inferencing the whole image.

How to send cropped image to detector 2 ?

may be you can refer to my post.
you should define your own logic in DsExampleProcess , parsing your own Region (ROI)
by cuda function or cpu func.
have a fun :)))
