vision-agents-plugins-ultralytics 0.5.3

Ultralytics YOLO plugin for GetStream

Ultralytics Plugin

This plugin provides YOLO-based pose detection capabilities for vision-agents using the Ultralytics YOLO library.

Features

• Real-time pose detection using YOLO models
• Hand and wrist tracking with detailed connections
• Video processing with pose annotations
• Configurable confidence thresholds and processing intervals
• Support for both CPU and GPU inference

Installation

uv add "vision-agents[ultralytics]"
# or directly
uv add vision-agents-plugins-ultralytics

Usage

from vision_agents.plugins import ultralytics

# Create a YOLO pose processor
processor = ultralytics.YOLOPoseProcessor(
    model_path="yolo11n-pose.pt",
    conf_threshold=0.5,
    device="cpu",
    enable_hand_tracking=True,
    enable_wrist_highlights=True
)

Configuration

• model_path: Path to YOLO pose model file (default: "yolo11n-pose.pt")
• conf_threshold: Confidence threshold for pose detection (default: 0.5)
• imgsz: Image size for YOLO inference (default: 512)
• device: Device to run inference on ('cpu' or 'cuda')
• max_workers: Number of worker threads for processing (default: 2)
• interval: Processing interval in seconds (0 for every frame)
• enable_hand_tracking: Whether to draw detailed hand connections
• enable_wrist_highlights: Whether to highlight wrist positions
