Struct CroppingStageProcessor

pub struct CroppingStageProcessor;

Expand description

Processor for text box cropping stage.

This processor encapsulates the logic for:

Cropping text boxes from images (both rotated and regular bounding boxes)
Parallel processing based on configurable thresholds
Consistent error handling and metrics collection

Implementations§

impl CroppingStageProcessor

pub fn process_single( image: &RgbImage, text_boxes: &[BoundingBox], config: Option<&CroppingConfig>, ) -> Result<StageResult<CroppingResult>, OCRError>

Process text box cropping for a single image.

§Arguments

image - The source image to crop from
text_boxes - Vector of bounding boxes to crop
config - Configuration for cropping processing

§Returns

A StageResult containing the cropping result and processing metrics

pub fn process_single_with_policy( image: &RgbImage, text_boxes: &[BoundingBox], config: Option<&CroppingConfig>, policy_threshold: Option<usize>, ) -> Result<StageResult<CroppingResult>, OCRError>

Process text box cropping for a single image with policy threshold.

§Arguments

image - The source image to crop from
text_boxes - Vector of bounding boxes to crop
config - Optional configuration for cropping processing
policy_threshold - Optional threshold from parallel policy

§Returns

A StageResult containing the cropping results and processing metrics

pub fn process_batch( images_and_boxes: Vec<(&RgbImage, &[BoundingBox])>, config: Option<&CroppingConfig>, ) -> Result<StageResult<Vec<CroppingResult>>, OCRError>

Process text box cropping for multiple images.

§Arguments

images_and_boxes - Vector of (image, text_boxes) pairs to process
config - Configuration for cropping processing

§Returns

A StageResult containing the cropping results and processing metrics

pub fn process_batch_with_policy( images_and_boxes: Vec<(&RgbImage, &[BoundingBox])>, config: Option<&CroppingConfig>, _policy_threshold: Option<usize>, ) -> Result<StageResult<Vec<CroppingResult>>, OCRError>

Process text box cropping for multiple images with policy threshold.

§Arguments

images_and_boxes - Vector of (image, text_boxes) pairs to process
config - Configuration for cropping processing
policy_threshold - Optional threshold from parallel policy

§Returns

A StageResult containing the cropping results and processing metrics
