Ocrs
This project is a terminal-based optical character recognition engine that uses neural network models to extract text and spatial layout data from images. It functions as both a command-line utility for automated text processing and a library for integrating machine learning-powered recognition into broader workflows.
The engine distinguishes itself through a modular processing pipeline that supports custom model loading and memory-mapped weight initialization for efficient execution. It preserves document structure by tracking precise geometric coordinates for every detected text element, and it allows for output refinement through character-level validation rules.
The system includes comprehensive tools for image ingestion, including direct capture from system clipboards and browser content. It provides diagnostic capabilities by generating visual overlays and intermediate processing artifacts to verify recognition accuracy and troubleshoot pipeline performance.
The software is distributed as a static binary to ensure portability across environments without requiring external dependencies.
