Usage Examples

!!! example "Region counting using Ultralytics YOLO"

=== "Python"

     ```python
     import cv2

     from ultralytics import solutions

     cap = cv2.VideoCapture("path/to/video.mp4")
     assert cap.isOpened(), "Error reading video file"

     # Pass region as list
     # region_points = [(20, 400), (1080, 400), (1080, 360), (20, 360)]

     # Pass region as dictionary
     region_points = {
         "region-01": [(50, 50), (250, 50), (250, 250), (50, 250)],
         "region-02": [(640, 640), (780, 640), (780, 720), (640, 720)],
     }

     # Video writer
     w, h, fps = (int(cap.get(x)) for x in (cv2.CAP_PROP_FRAME_WIDTH, cv2.CAP_PROP_FRAME_HEIGHT, cv2.CAP_PROP_FPS))
     video_writer = cv2.VideoWriter("region_counting.avi", cv2.VideoWriter_fourcc(*"mp4v"), fps, (w, h))

     # Initialize region counter object
     regioncounter = solutions.RegionCounter(
         show=True,  # display the frame
         region=region_points,  # pass region points
         model="yolo11n.pt",  # model for counting in regions i.e yolo11s.pt
     )

     # Process video
     while cap.isOpened():
         success, im0 = cap.read()

         if not success:
             print("Video frame is empty or processing is complete.")
             break

         results = regioncounter(im0)

         # print(results)  # access the output

         video_writer.write(results.plot_im)

     cap.release()
     video_writer.release()
     cv2.destroyAllWindows()  # destroy all opened windows
     ```
