I am trying to do preprocessing after the primary engine and before the secondary engine. The preprocessing involves cropping one class of the detected object into half by keeping only the top right. Can you suggest the best way to do this?

1.We cannot support nvpreprocess plugin before sgie until deepstream 6.2. So we sugget you update your deepstream version to 6.2.
2.If you just want to process the frame after the pgie, you can add a probe function or add a video-template plugin after pgie to process the frame.

We are unable to upgrade to DeepStream 6.2 for our solutions at this time. Could you please suggest preprocessing techniques that we can use with DeepStream 6.0? Specifically, we are looking to crop the detected object from the primary model into half, keeping only the right side of the cropped object, and feed it to a secondary model. Can you please suggest how we can achieve this?

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks

OK. You can use video-template plugin to add your own processing before sgie.
About how to use the plugin, you can refer to our demo:
