Smart Polygon (Legacy)
Blog post from Roboflow
Roboflow has introduced an improved Smart Polygon feature in their annotation tool, Roboflow Annotate, leveraging the Segment Anything Model (SAM) to assist users in generating polygon annotations for objects within images. By selecting the Smart Polygon option from the labeling toolbar, users can click on the center of an object to create an initial polygon outline, which can be refined by adding negative points to areas that should not be highlighted. Users can adjust the polygon's vertices through different options like Convex Hull, Smooth, and Complex labels, and undo any misplaced points. This tool is particularly beneficial for labeling semantic segmentation data, and users can ensure proper mask stacking by arranging objects' z-indexes through the Layers tab, which is accessible across all Roboflow project types.
