Property Definition¶
Version v1¶
Define a field using properties from previous workflow steps.
Example use-cases: * extraction of all class names for object-detection predictions * extraction of class / confidence from classification result * extraction ocr text from OCR result
Type identifier¶
Use the following identifier in step "type" field: roboflow_core/property_definition@v1to add the block as
as step in your workflow.
Properties¶
| Name | Type | Description | Refs |
|---|---|---|---|
name |
str |
The unique name of this step.. | ❌ |
operations |
List[Union[ClassificationPropertyExtract, DetectionsFilter, DetectionsOffset, DetectionsPropertyExtract, DetectionsRename, DetectionsSelection, DetectionsShift, Divide, ExtractDetectionProperty, ExtractImageProperty, LookupTable, Multiply, NumberRound, NumericSequenceAggregate, RandomNumber, SequenceAggregate, SequenceApply, SequenceLength, SequenceMap, SortDetections, StringMatches, StringSubSequence, StringToLowerCase, StringToUpperCase, ToBoolean, ToNumber, ToString]] |
List of operations to perform on data to generate output. | ❌ |
The Refs column marks possibility to parametrise the property with dynamic values available
in workflow runtime. See Bindings for more info.
