Relative Static Crop¶
Class: RelativeStaticCropBlockV1
Crop a Region of Interest (RoI) from an image, using relative coordinates.
This is useful when placed after an ObjectDetection block as part of a multi-stage workflow. For example, you could use an ObjectDetection block to detect objects, then the RelativeStaticCrop block to crop objects, then an OCR block to run character recognition on each of the individual cropped regions.
Type identifier¶
Use the following identifier in step "type" field: roboflow_core/relative_statoic_crop@v1to add the block as
as step in your workflow.

Enter a unique identifier for this step.. | ❌ |
x_center |
float |
Center X of static crop (relative coordinate 0.0-1.0). | ✅ |
y_center |
float |
Center Y of static crop (relative coordinate 0.0-1.0). | ✅ |
width |
float |
Width of static crop (relative value 0.0-1.0). | ✅ |
height |
float |
Height of static crop (relative value 0.0-1.0). | ✅ |
The Refs column marks possibility to parametrise the property with dynamic values available
in workflow runtime. See Bindings for more info.
