Usage

Installation

pip install ultralytics

Python API

from ultralytics import YOLO

# Load CourtSide Computer Vision v1 model
model = YOLO('Davidsv/CourtSide-Computer-Vision-v1')

# Predict on image
results = model.predict('tennis_match.jpg', conf=0.25)

# Display results
results[0].show()

# Get detections by class
for box in results[0].boxes:
    cls = int(box.cls[0])
    conf = float(box.conf[0])
    class_name = model.names[cls]
    print(f"{class_name}: {conf:.2%}")

Video Processing

from ultralytics import YOLO

model = YOLO('Davidsv/CourtSide-Computer-Vision-v1')

# Process video with tracking
results = model.track(
    source='tennis_match.mp4',
    conf=0.25,
    tracker='bytetrack.yaml',
    save=True
)

Command Line

# Predict on image
yolo detect predict model=Davidsv/CourtSide-Computer-Vision-v1 source=image.jpg conf=0.25

# Predict on video
yolo detect predict model=Davidsv/CourtSide-Computer-Vision-v1 source=video.mp4 conf=0.25 save=True

# Track objects in video
yolo detect track model=Davidsv/CourtSide-Computer-Vision-v1 source=video.mp4 conf=0.25

Recommended Hyperparameters

Inference Settings

# Balanced (recommended)
conf_threshold = 0.25  # Confidence threshold
iou_threshold = 0.45   # NMS IoU threshold

# High precision (fewer false positives)
conf_threshold = 0.40
iou_threshold = 0.45

# High recall (detect more objects)
conf_threshold = 0.15
iou_threshold = 0.40

Use Cases

• Real-time tennis match analysis
• Player position and movement tracking
• Ball trajectory prediction
• Court zone occupancy analysis
• Automated highlight generation
• Swing detection and technique analysis
• Sports analytics dashboards
• Training video analysis
