//! Image processing utilities for OCR systems.
//!
//! This module provides a collection of image processing functions and utilities
//! specifically designed for OCR (Optical Character Recognition) systems. It includes
//! functionality for image resizing, normalization, geometric operations, text decoding,
//! and post-processing of OCR results.
//!
//! # Modules
//!
//! * `aspect_ratio_bucketing` - Aspect ratio bucketing for efficient batch processing
//! * `decode` - Text decoding utilities for converting model predictions to readable text
//! * `geometry` - Geometric primitives and algorithms for OCR processing
//! * `normalization` - Image normalization utilities for preparing images for OCR models
//! * `db_postprocess` - DB detection post-processing
//! * `uvdoc_postprocess` - UVDoc rectification post-processing
//! * `formula_preprocess` - Formula recognition preprocessing
//! * `layout_postprocess` - Layout detection post-processing
//! * `resize_detection` - Resizing for detection models
//! * `resize_recognition` - Resizing for recognition models
//! * `types` - Type definitions used across the processors module
