Model Comparison Visualization

Class: ModelComparisonVisualizationBlockV1

Source: inference.core.workflows.core_steps.visualizations.model_comparison.v1.ModelComparisonVisualizationBlockV1

The ModelComparisonVisualization block draws all areas predicted by neither model with a specified color, lets overlapping areas of the predictions shine through, and colors areas predicted by only one model with a distinct color.

Type identifier

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

Properties

Name	Type	Description	Refs
name	str	Enter a unique identifier for this step..	❌
copy_image	bool	Enable this option to create a copy of the input image for visualization, preserving the original. Use this when stacking multiple visualizations..	✅
color_a	str	Color of the areas Model A predicted that Model B did not...	✅
color_b	str	Color of the areas Model B predicted that Model A did not..	✅
background_color	str	Color of the areas neither model predicted..	✅
opacity	float	Transparency of the overlay..	✅

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