Description

@mftee

Create high-performance OCR library with Tesseract bindings

Description:
Build a Rust-based OCR engine that processes images and extracts text with high accuracy.

Requirements:

  • Tesseract bindings for Rust
  • Image preprocessing (grayscale, noise reduction, deskew)
  • Multi-language support
  • Batch processing capability
  • Confidence scores for extracted text
  • Bounding box detection
  • CLI tool for standalone usage
  • Node.js FFI bindings
  • Performance optimizations
  • Thread-safe operations

Acceptance Criteria:

  • OCR accuracy matches or exceeds Tesseract.js
  • Preprocessing improves accuracy
  • Processes images 2x faster than JS alternatives
  • CLI tool processes batches
  • FFI bindings work correctly
  • Comprehensive tests with test images
  • Documentation with examples
