Yes, nvdspreprocess will prepare the input tensor. Can you add bindings for the NvDsPreProcessBatchMeta by yourself?

you could use a probe similar to this blog. [image] Xavier NX-DeepStream 5.0 #4 - Handling Primary, Secondary Inference Results Blog about NVidia Jetson Nano, TX2.

Thank you for the help, but this blog-post tells us how to get the object’s metadata. I want to grab the input of nvinfer, e.g. what is the actual image going as the input of sgie

Can you share why you need dump the input of nvinfer?

My sgie is not giving the required accurate results, so I just wanted to check what is it’s input? how the images are preprocessed just before going to sgie-nvinfer.

Thank you, setting these parameters improves performance a lot… But I still want to know if there is a way to extract the input of nvinfer or it is not possible in python right now?

[image] curious_cat: you could use a probe similar to this blog. NVIDIA Jetson and Raspberry Pi: Xavier NX-DeepStream 5.0 #4 - Handling Primary, Secondary Inference Results It gives segmentation fault when I try to convert RGBA to BGR using opencv

It worked when I changed mem type of nvvidconv to Unified CUDA Memory.

How are you going with this? I’m trying to test the same. My model was trained using pytorch normalization and resize. So I’d like to verify the pre-processing nvinfer is doing is equivalent. The nvinfer module includes normalization and I think also resizing by default. This happens inside the…

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
