Struct PreprocessPipelineBuilder 

pub struct PreprocessPipelineBuilder { /* private fields */ }

Builder for common preprocessing pipelines.

Provides a fluent interface for constructing preprocessing operations without duplicating code across adapters.

Example

// let tensor = PreprocessPipelineBuilder::new()
//     .rgb_images(images)
//     .resize(&resizer)
//     .normalize(&normalizer)
//     .build()?;

Implementations

impl PreprocessPipelineBuilder

pub fn new() -> PreprocessPipelineBuilder

Creates a new preprocessing pipeline builder.

pub fn rgb_images( self, images: Vec<ImageBuffer<Rgb<u8>, Vec<u8>>>, ) -> PreprocessPipelineBuilder

Sets the input RGB images.

pub fn dynamic_images( self, images: Vec<DynamicImage>, ) -> PreprocessPipelineBuilder

Sets the input dynamic images.

pub fn to_dynamic(self) -> PreprocessPipelineBuilder

Converts RGB images to dynamic images.

pub fn resize<R>( self, resizer: &R, ) -> Result<PreprocessPipelineBuilder, OCRError>

where R: ResizeOperation,

Applies a resize operation.

pub fn normalize( self, normalizer: &NormalizeImage, ) -> Result<ArrayBase<OwnedRepr<f32>, Dim<[usize; 4]>>, OCRError>

Normalizes images to a tensor.

pub fn build( self, normalizer: &NormalizeImage, ) -> Result<ArrayBase<OwnedRepr<f32>, Dim<[usize; 4]>>, OCRError>

Builds the final tensor (alias for normalize for consistency).

impl Default for PreprocessPipelineBuilder

fn default() -> PreprocessPipelineBuilder

Returns the “default value” for a type.
