Image Annotation service
Bounding Box Annotation

Bounding Box Annotation

Bounding Box Annotation involves precisely drawing rectangles around objects of interest in images. This annotation technique is fundamental for training object detection models. Outlining the exact boundaries of objects facilitates accurate localization and recognition in computer vision applications, such as autonomous vehicles and security surveillance.

polyline annotation

Polygon and Polyline Annotation

Polygon and Polyline Annotation allow the annotation of irregular shapes and contours in images. It is beneficial for scenarios where objects have complex boundaries. This annotation method is employed in applications such as geographic information systems (GIS), where it aids in mapping and environmental monitoring by capturing intricate details of land cover, terrain, or objects with non-rectangular shapes.

Skeleton Annotation

Skeleton Annotation involves outlining and annotating skeletal structures within images. This annotation category is vital for tasks like pose estimation and human movement analysis in fields such as sports biomechanics or fitness tracking. Defining the underlying structure of objects provides a foundation for understanding and analyzing movement patterns, enhancing applications like virtual try-ons in the fashion industry.
