Polygon Visualization¶

Version v1¶

The PolygonVisualization block uses a detections from an instance segmentation to draw polygons around objects using sv.PolygonAnnotator.

Type identifier¶

Use the following identifier in step "type" field: roboflow_core/polygon_visualization@v1to add the block as as step in your workflow.

Properties¶

The Refs column marks possibility to parametrise the property with dynamic values available in workflow runtime. See Bindings for more info.
