How to reduce the font size of inference detection categories and values?

❔Question

Hello author, I am using detect.py to infer using images smaller than 640 pixels, and my image is 256 pixels. The inference process is successful, I would like to know how to reduce the font size of the detection results (detection category and detection value), they are filling up my graph and blocking a large area, how to solve it well?

Additional context

None.

You can reduce the line thickness by changing this line in detect.py:

plot_one_box(xyxy, im0, label=label, color=colors[int(cls)], line_thickness=3)

Try changing it to line_thickness=2 or line_thickness=1.

The font size is determined relative to that line_thickness value. That code lives in plot_one_box() in utils/plots.py.

@adrianholovaty Thank you! Very quick reply, I'll give it a try!
Otherwise the color of the detection box is different every time I test and I'm fainting...
