## Parameter Details

The `LabelRecognizerTask` includes the following sections:

* [RegionPredetectionSection](https://www.dynamsoft.com/capture-vision/docs/core/parameters/reference/label-recognizer-task-settings/section-regions-predetection.md) (`ST_REGION_PREDETECTION`)
  * Designed to find regions of interest (ROIs) and thus ignore other parts of the image during subsequent processing.
* [TextLineLocalizationSection](https://www.dynamsoft.com/capture-vision/docs/core/parameters/reference/label-recognizer-task-settings/section-text-lines-localization.md) (`ST_TEXT_LINE_LOCALIZATION`)
  * Designed to detect the exact locations of text-lines.
* [TextLineRecognitionSection](https://www.dynamsoft.com/capture-vision/docs/core/parameters/reference/label-recognizer-task-settings/section-text-lines-recognition.md) (`ST_TEXT_LINE_RECOGNITION`)
  * Designed to recognize the text from the text-line areas identified in the previous `TextLineLocalizationSection` section.
