I’m developing on Deepstream. My PGIE is a yolox model . My SGIE is a UNET model . The pipeline detect multi objects on frame and transform every object to unet.
The origin bbox is blue line , but I want to expand the bbox to red line before sgie .For example left-10 ,top-10,width+20 ,height+20 . And shrink the bbox to orgin after sgie.
I’m modifying the gst-nvinfer pulgin and find gst_nvinfer_process_objects funciton doing some work. Is there any example code could realize my idea?

We don’t have such example code now. You can try to get the object paras from a probe function and change the coordinates paras by yourself.

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.

Another idea is you can just change the BBOX coordinates in the output parser of your yolox model
