## Description

Tesseract-OCR-iOS is a native integration of the Tesseract engine for iOS applications. It provides on-device image recognition to identify and extract printed text from images, converting them into editable strings.

The project enables local device execution, meaning image processing and text extraction occur entirely on the hardware without the use of external cloud services or network requests. It utilizes a C++ wrapper and an Objective-C bridge to interface high-level iOS APIs with the underlying Tesseract engine and Leptonica image processing library.

The library supports document digitization workflows and the development of accessibility tools that read text from the camera or photos. It manages the loading of language-specific trained data files directly from the application bundle.
