Crate oxify_connect_vision 

oxify-connect-vision

Vision/OCR connector for OxiFY workflows.

This crate provides OCR (Optical Character Recognition) capabilities for extracting text from images and documents.

Features

• Mock provider: For testing and development
• Tesseract: Traditional OCR engine (requires system installation)
• Surya: Deep learning OCR with layout analysis (ONNX)
• PaddleOCR: High-quality multilingual OCR (ONNX)
• Google Cloud Vision: Cloud-based OCR with Google’s Vision API

Usage

use oxify_connect_vision::{providers, VisionProvider};

// Create a mock provider for testing
let provider = providers::MockVisionProvider::new();

// Process an image
let result = provider.process_image(&image_bytes).await?;

println!("Extracted text: {}", result.text);
println!("Markdown: {}", result.markdown);

Feature Flags

• mock (default): Enable mock provider
• tesseract: Enable Tesseract OCR support
• surya: Enable Surya OCR (requires ONNX models)
• paddle: Enable PaddleOCR (requires ONNX models)
• google-vision: Enable Google Cloud Vision API support
• cuda: Enable CUDA GPU acceleration
• coreml: Enable CoreML GPU acceleration (macOS)
• all-providers: Enable all OCR providers
