How to add an extra "image" field to NvDsVehicleObject in python and send it via Redis message broker

I get a crop frame from my model and I want to add it to NvDsVehicleObject and then send it to redis message broker.

I found a discussion How to send cropped image through msgbroker using python - #18 by xya22er but i still don’t understand how to add the field images in NvDsVehicleObject
