Trait for postprocessing operations.

This trait handles converting raw inference outputs into meaningful results (decoding, filtering, formatting, etc.).

Required Associated Types

type Config: Send + Sync + Debug

Configuration type for postprocessing

type InferenceOutput: Send + Sync + Debug

Input type from inference engine

type PreprocessOutput: Send + Sync + Debug

Preprocessed data type for context

type Result: Send + Sync + Debug

Final result type after postprocessing

Required Methods

fn postprocess( &self, inference_output: Self::InferenceOutput, preprocess_output: Option<&Self::PreprocessOutput>, batch_data: &BatchData, raw_images: Vec<ImageBuffer<Rgb<u8>, Vec<u8>>>, config: Option<&Self::Config>, ) -> Result<Self::Result, OCRError>

Postprocess inference output into final results.

Arguments

• inference_output - Raw output from inference engine
• preprocess_output - Optional preprocessed data for context
• batch_data - Batch metadata
• raw_images - Original input images
• config - Optional configuration for postprocessing

Returns

Final processed result or an error

fn empty_result(&self) -> Result<Self::Result, OCRError>

Create an empty result for when no input is provided.

Returns

Empty result instance

Provided Methods

fn postprocessing_info(&self) -> String

Get information about the postprocessing operations.

Returns

String describing postprocessing operations

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
