Bounding Rectangle

Class: BoundingRectBlockV1

Source: inference.core.workflows.core_steps.transformations.bounding_rect.v1.BoundingRectBlockV1

The BoundingRect is a transformer block designed to simplify polygon to the minimum boundig rectangle. This block is best suited when Zone needs to be created based on shape of detected object (i.e. basketball field, road segment, zebra crossing etc.) Input detections should be filtered beforehand and contain only desired classes of interest. Resulsts are stored in sv.Detections.data

Type identifier

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

Properties

Name	Type	Description	Refs
name	str	Enter a unique identifier for this step..	❌

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