Smart OCR Skill

Overview

This skill enables intelligent text extraction from images and scanned documents using PaddleOCR - a leading OCR engine supporting 100+ languages. Extract text from photos, screenshots, scanned PDFs, and handwritten documents with high accuracy.

How to Use

1. Provide the image or scanned document
2. Optionally specify language(s) to detect
3. I'll extract text with position and confidence data

Example prompts:

• "Extract all text from this screenshot"
• "OCR this scanned PDF document"
• "Read the text from this business card photo"
• "Extract Chinese and English text from this image"

Domain Knowledge

PaddleOCR Fundamentals

from paddleocr import PaddleOCR

# Initialize OCR engine
ocr = PaddleOCR(use_angle_cls=True, lang='en')

# Run OCR on image
result = ocr.ocr('image.png', cls=True)

# Result structure: [[box, (text, confidence)], ...]
for line in result[0]:
    box = line[0]      # [[x1,y1], [x2,y2], [x3,y3], [x4,y4]]
    text = line[1][0]  # Extracted text
    conf = line[1][1]  # Confidence score
    print(f"{text} ({conf:.2f})")

Supported Languages

# Common language codes
languages = {
    'en': 'English',
    'ch': 'Chinese (Simplified)',
    'cht': 'Chinese (Traditional)',
    'japan': 'Japanese',
    'korean': 'Korean',
    'french': 'French',
    'german': 'German',
    'spanish': 'Spanish',
    'russian': 'Russian',
    'arabic': 'Arabic',
    'hindi': 'Hindi',
    'vi': 'Vietnamese',
    'th': 'Thai',
    # ... 100+ languages supported
}

# Use specific language
ocr = PaddleOCR(lang='ch')  # Chinese
ocr = PaddleOCR(lang='japan')  # Japanese
ocr = PaddleOCR(lang='multilingual')  # Auto-detect
