What Is Polygon Annotation? How It Works and Why It Matters in AI
Artificial intelligence (AI) and machine learning (ML) technologies are rapidly transforming industries, enabling systems to perceive, process, and act on data. A cornerstone of these advancements is data annotation services , a critical process of labeling datasets to train machine learning algorithms effectively. Among the various annotation techniques, polygon annotation stands out as a highly effective method for precise object detection and classification in images. Understanding Polygon Annotation Polygon annotation is a technique where objects within an image are outlined using multiple vertices to create a closed shape. Unlike bounding boxes, which provide rectangular annotations, polygon annotations conform to the exact edges of an object, ensuring a higher level of accuracy. This precision is especially crucial for applications that involve irregularly shaped objects, such as cars in traffic scenes, animals in wildlife photography, or organs in medical imaging.
