Object Detection with YOLO

Beyond classification

Classification says what is in an image; object detection says what and where, drawing boxes around each object. YOLO ("You Only Look Once") does it fast enough for video.

from ultralytics import YOLO
model = YOLO("yolov8n.pt")
results = model("street.jpg")
results[0].show()   # boxes + labels

Going further

Fine-tune on your own labeled images (annotate with Roboflow or Label Studio) to detect custom objects. Watch confidence thresholds and non-max suppression settings to balance precision and recall.
