+# dora-cotracker
+
+A Dora node that implements real-time object tracking using Facebook's CoTracker model. The node supports both interactive point selection via clicking and programmatic point input through Dora's messaging system.
+
+## Features
+
+- Real-time object tracking using CoTracker
+- Support for multiple tracking points
+- Interactive point selection via mouse clicks
+- Programmatic point input through Dora messages
+- Visualization of tracked points with unique identifiers
+
+## Getting Started
+
+### Installation
+
+Install using uv:
+
+```bash
+uv venv -p 3.11 --seed
+uv pip install -e .
+```
+
+## Demo Video
+
+Watch a demonstration of the dora-cotracker node in action:
+
+[![Dora CoTracker Demo](https://img.youtube.com/vi/1VmC1BNq6J0/0.jpg)](https://youtu.be/1VmC1BNq6J0)
+
+The video shows:
+- Setting up the node
+- Interactive point selection
+- Real-time tracking performance
+
+### Basic Usage
+
+1. Create a YAML configuration file (e.g., `demo.yml`):
+
+```yaml
+nodes:
+  - id: camera
+    build: pip install opencv-video-capture
+    path: opencv-video-capture
+    inputs:
+      tick: dora/timer/millis/100
+    outputs:
+      - image
+    env:
+      CAPTURE_PATH: "0"
+      ENCODING: "rgb8"
+      IMAGE_WIDTH: "640"
+      IMAGE_HEIGHT: "480"
+
+  - id: tracker
+    build: pip install -e dora-cotracker
+    path: dora-cotracker
+    inputs:
+      image: camera/image
+      points_to_track: input/points_to_track
+    outputs:
+      - tracked_image
+      - tracked_points
+
+  - id: display
+    build: pip install dora-rerun
+    path: dora-rerun
+    inputs:
+      image: camera/image
+      tracked_image: tracker/tracked_image
+```
+
+*Note* - this only has the cv2 as an input source. see below to add your nodes workflow and pass points directly.
+
+2. Run the demo:
+
+```bash
+dora run demo.yml --uv
+```
+
+## Usage Examples
+
+### 1. Interactive Point Selection
+Click points directly in the "Raw Feed" window to start tracking them:
+- Left-click to add tracking points
+- Points will be tracked automatically across frames
+- Each point is assigned a unique identifier (C0, C1, etc. for clicked points and I0, I1, etc for input points)
+
+### 2. Dynamic Point Integration
+The node can receive tracking points from other models or nodes in your pipeline. Common use cases include:
+
+- Tracking YOLO detection centroids
+- Following pose estimation keypoints
+- Monitoring segmentation mask centers
+- Custom object detection points
+
+example showing how to send tracking points through Dora messages using a custom input node:
+
+```python
+import numpy as np
+import pyarrow as pa
+from dora import Node
+
+class PointInputNode:
+    def __init__(self):
+        self.node = Node("point-input")
+    
+    def send_points(self, points):
+        """
+        Send points to tracker
+        Args:
+            points: Nx2 array of (x,y) coordinates
+        """
+        points = np.array(points, dtype=np.float32)
+        self.node.send_output(
+            "points_to_track",
+            pa.array(points.ravel()),
+            {
+                "num_points": len(points),
+                "dtype": "float32", 
+                "shape": (len(points), 2)
+            }
+        )
+
+    def run(self):
+        # Example: Track 3 points
+        points = np.array([
+            [320, 240],  # Center
+            [160, 120],  # Top-left
+            [480, 360]   # Bottom-right
+        ])
+        self.send_points(points)
+```
+
+
+
+To connect your existing node that outputs tracking points with the CoTracker node, add the following to your YAML configuration:
+
+```yaml
+nodes:
+  # Your existing point source node (e.g., YOLO detector, pose estimator, etc.)
+  - id: point_source
+    build: pip install your-node  # Replace with your node's name
+    path: your-point-source-node  # Replace with your node's path
+    inputs:
+      image: camera/image  # If your node needs image input
+    outputs:
+      - points_to_track    # Must output points in required format
+
+  # CoTracker node configuration
+  - id: tracker
+    build: pip install dora-cotracker
+    path: dora-cotracker
+    inputs:
+      image: camera/image
+      points_to_track: point_source/points_to_track  # Connect to your point source
+    outputs:
+      - tracked_image
+      - tracked_points
+
+  # Optional visualization
+  - id: display
+    build: pip install dora-rerun
+    path: dora-rerun
+    inputs:
+      image: camera/image
+      tracked_image: tracker/tracked_image
+```
+
+Your point source node must output points in the following format:
+- Topic name: `points_to_track`
+- Data: Flattened numpy array of x,y coordinates
+- Metadata:
+  ```python
+  {
+      "num_points": len(points),  # Number of points
+      "dtype": "float32",        # Data type
+      "shape": (N, 2)           # N points, 2 coordinates each
+  }
+  ```
+
+Example point source implementations:
+- YOLO detection centroids
+- Pose estimation keypoints
+- Face landmark detectors
+- Custom object detectors
+
+For dynamic updates, send new points whenever your source node processes a new frame. The tracker will maintain temporal consistency between updates.
+**
