Does the secondary GIE resizes its input to match classifier input dimension?

Please provide complete information as applicable to your setup.

• DeepStream Version: 5.0

• Issue Type( questions, new requirements, bugs): question

I have classifier trained via TLT, before training, all images are resized to match the classifier input size so I wonder in deepstream, beside cropping (according to the metadata from primary detector), does the secondary GIE does any resizing internally before perform classification?

Yes, nvinfer will do the resize based on the infer-dims you specified in nvinfer config file , pls check https://docs.nvidia.com/metropolis/deepstream/dev-guide/text/DS_plugin_gst-nvinfer.html for more details
