Region is Movable

During video playback, you can interactively move the region within the video by clicking and dragging using the left mouse button.

# Save results
python --source "path/to/video.mp4" --save-img

# Run model on CPU
python --source "path/to/video.mp4" --device cpu

# Change model file
python --source "path/to/video.mp4" --weights "path/to/"

# Detect specific classes (e.g., first and third classes)
python --source "path/to/video.mp4" --classes 0 2

# View results without saving
python --source "path/to/video.mp4" --view-img
