Result Processor

Serves as the base class for all result processors, which define post-processing operations applied to each output value produced by an Data Type in Grooper.

Remarks

Result Processors are used in Grooper to perform additional processing on the results generated by extractors, enabling advanced workflows such as value normalization, filtering, region placement, and transformation of extracted data.

How Result Processors Work

After an extractor (such as a Value Reader or Data Type) identifies and outputs values from a document, these results are passed through one or more Result Processors. Each processor can modify, filter, or augment the results before they are finalized and made available for downstream use.

Derived Types

There are 3 implementations of Result Processor.

OCR Reader	Extracts text from a region near each Data Type output instance using OCR or existing OCR results.
OMR Reader	Detects and reads optical marks (checkboxes) associated with each extractor result using OMR.
Place Zone	Places a zone (region) relative to each output instance for downstream extraction or processing.
