Gst-nvinfer default configuration values

Hi, I am looking for the default values that are used for all parameters if you do not specify them in pgie.txt.

When looking at the documentation it is not explicitly mentioned.

For example, the nms-iou-threshold, what default value is used?

The only thing that is shown in the documentation is:

| Name              | Description    | Type and Range  | Example Notes         | (Primary/Secondary) |
| nms-iou-threshold | Maximum IOU... | Float, ≥0       | nms-iou-threshold=0.2 | Object detector Both |

The column ‘Example Notes’ shows an example, but this is not the default value - or am I wrong?

Without knowing the default values I think everyone is forced to define every parameter with a value. Otherwise we do not know what we are doing…

I think you can check the code directly.
Its at /opt/nvidia/deepstream/deepstream-6.3/sources/gst-plugins/gst-nvinfer/gstnvinfer_property_parser.h

Based on the values defined here, the default nms-iou-threshold seems to be 0.3

#define DEFAULT_NMS_IOU_THRESHOLD 0.3
