• Pre-Process

  To ensure fair benchmark comparisons with YOLOX, BGR to RGB conversion processing and normalization by division by 255.0 are added to the model input section. In addition, a resizing process for input images has been added to improve operational flexibility. Thus, in any model, inferences can be made at any image size. The string 1x3x{H}x{W} at the end of the file name does not indicate the input size of the image, but the processing resolution inside the model. Therefore, the smaller the values of {H} and {W}, the lower the computational cost and the faster the inference speed. Models with larger values of {H} and {W} increase the computational cost and decrease the inference speed. Since the concept is different from the resolution of an image, any size image can be batch processed. e.g. 240x320, 480x640, 720x1280, ...

  

• Post-Process

  Because I add my own post-processing to the end of the model, which can be inferred by TensorRT, CUDA, and CPU, the benchmarked inference speed is the end-to-end processing speed including all pre-processing and post-processing. EfficientNMS in TensorRT is very slow and should be offloaded to the CPU.

  • NMS default parameter

    param	value	note
    max_output_boxes_per_class	20	Maximum number of outputs per class of one type. 20 indicates that the maximum number of people detected is 20, the maximum number of heads detected is 20, and the maximum number of hands detected is 20. The larger the number, the more people can be detected, but the inference speed slows down slightly due to the larger overhead of NMS processing by the CPU. In addition, as the number of elements in the final output tensor increases, the amount of information transferred between hardware increases, resulting in higher transfer costs on the hardware circuit. Therefore, it would be desirable to set the numerical size to the minimum necessary.
    iou_threshold	0.40	A value indicating the percentage of occlusion allowed for multiple bounding boxes of the same class. 0.40 is excluded from the detection results if, for example, two bounding boxes overlap in more than 41% of the area. The smaller the value, the more occlusion is tolerated, but over-detection may increase.
    score_threshold	0.25	Bounding box confidence threshold. Specify in the range of 0.00 to 1.00. The larger the value, the stricter the filtering and the lower the NMS processing load, but in exchange, all but bounding boxes with high confidence values are excluded from detection. This is a parameter that has a very large percentage impact on NMS overhead.

  • Change NMS parameters

    Use PINTO0309/sam4onnx to rewrite the NonMaxSuppression parameter in the ONNX file.

    For example,

    pip install onnxsim==0.4.33 \
    && pip install -U simple-onnx-processing-tools \
    && pip install -U onnx \
    && python -m pip install -U onnx_graphsurgeon \
        --index-url https://pypi.ngc.nvidia.com

  • Post-processing structure

    PyTorch alone cannot generate this post-processing. For operational flexibility, EfficientNMS is not used.
