💡 Example Usage

from khmer_nid_detector import detect_card_type, process_nid_card

with open("nid_card.jpg", "rb") as f:
    image_bytes = f.read()

card_type = detect_card_type(image_bytes)
print(f"Detected card type: {card_type}")

if card_type == "nid_card":
    result = process_nid_card(image_bytes)

    if result.success:
        print(f"NID Number: {result.nid_number}")
        print(f"Name: {result.name}")
        print(f"Date of Birth: {result.dob}")
        print(f"Is Khmer NID: {result.is_khmer_nid}")
        print(f"Message: {result.message}")
        print(f"Suggestion: {result.suggestion}")
    else:
        print(f"Error: {result.message}")

🧠 How It Works

1. Preprocessing: Cleans and enhances the input image.
2. Card Type Detection: Classifies the image into supported types.
3. Text Extraction (OCR): Extracts Khmer and English text using EasyOCR and Tesseract.
4. Information Parsing: Detects NID number, name, and date of birth.
