Why the Primary_Detector resnet10.caffemodel_b1_gpu0_int8.engine does not need a box parser and NMS?

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) GPU
• DeepStream Version 5.0
• JetPack Version (valid for Jetson only)
• TensorRT Version 7.0
• NVIDIA GPU Driver Version (valid for GPU only) T4
• Issue Type( questions, new requirements, bugs)
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description)

The following command can detect pedestrian and vehicle successfully.

However, why the Yolo detector need a box parser and NMS post-processing?

Up

It depends on the yolov5 model but not deepstream. yolov5/detect.py at master · ultralytics/yolov5 (github.com). Yolov5 is a classifier but not detector. Docker Hub

Yolov5 is not provided by Nvidia. Please refer to yolov5 resources for your questions.

Thanks, I will investgate the source code.
