I have a requirement for running a classifier on the bottom 20% of a given bounding box inferred by my object detection model. I plan to run the object detection model as the PGIE and the classifier as the SGIE. What are my options to do this ?

I dont want to start with making changes to the nvdspreprocess plugin, since it would require time investment to learn how the plugin works and adding relevant changes to the code. Is there an alternative, I was thinking if we could add a probe to the SGIE input buffer and within the probe we make c…

Ok, thanks for clarifying. Looking at the source code diagram given here DeepStream SDK FAQ , I should prepare a 'custom_transform ’ function I am guessing this relates to the “custom-input-transformation-function” parameter in the configuration file. Can you help me out with an example implementati…

I added my “custom-input-transformation-function” to /opt/nvidia/deepstream/deepstream/sources/gst-plugins/gst-nvdspreprocess/nvdspreprocess_lib/nvdspreprocess_lib.cpp . I ran make inside its parent folder /opt/nvidia/deepstream/deepstream/sources/gst-plugins/gst-nvdspreprocess . Ran my application …

The code is totally open source, please debug with your customized code.

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

You can customize the SGIE preprocess with Gst-nvdspreprocess — DeepStream documentation.
