Image Threshold¶

Version v1¶

Apply a threshold to an image. The image must be in grayscale.

Type identifier¶

Use the following identifier in step "type" field: roboflow_core/threshold@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.
