Polygon annotation is a technique used in computer vision to outline the exact shape of an object within an image by connecting multiple points to form a closed shape.
🔹 Key Features:
- Allows precise, pixel-level object boundaries.
- More accurate than bounding boxes for irregular or curved shapes.
- Composed of multiple (x, y) coordinates connected in sequence.
🔹 Use Cases:
Retail: Identifying product outlines in shelf images.
Autonomous driving: Labeling vehicles, pedestrians, and road features.
Medical imaging: Segmenting organs or tumors with high accuracy.
Aerial imagery: Mapping land, buildings, or vegetation.
