What is OCR?

Let’s discuss OCR technology a bit more. Regarding data extraction, OCR is the most essential technology today. We can use it to convert scanned or photographed documents into editable or searchable texts. This enables you to extract information like names, addresses, numbers, etc., for further processing. 

Early OCR systems read only one character at a time and supported only one language and one font. Also, they needed clean and high-resolution images to process. However, modern OCRs are capable of multilingual text extraction. Also, they support multiple fonts and can handle a wide range of images that are blurry, noisy and distorted more accurately.

We can use OCR technology in many different contexts. For example, we can use OCRs to extract items and prices from receipts or invoices for data entry, or you can save hours of time by converting a scanned book into digital text for editing or archiving. Also, you can extract data from user-uploaded documents such as CVs, certificates, and medical documents to update the databases.

Key features of multi-language JavaScript OCR API

This simple code example demonstrates how you could integrate the Filestack JavaScript OCR API into a chat application to recognize text from images or screenshots:

<!-- Include the Filestack JavaScript SDK in your HTML file -->
<script src="https://static.filestackapi.com/filestack-js/3.x.x/filestack.min.js"></script>

<script>
// Initialize the Filestack client
const client = filestack.init('YOUR_API_KEY');

// Function to upload an image and apply OCR
function processImageForOCR(imageFile) {
  // Upload the image to Filestack
  client.upload(imageFile)
    .then(response => {
      // Get the handle for the uploaded image
      const fileHandle = response.handle;

      // Apply OCR transformation on the uploaded image
      return client.transform(fileHandle, {
        ocr: { language: 'eng' } // Specify language or use auto-detection
      });
    })
    .then(ocrResult => {
      // Extract the recognized text from the response
      const recognizedText = ocrResult.data.text;
      console.log('Recognized Text:', recognizedText);

      // Use the recognized text in your chat application
      // For example, send it as a chat message or display it in the chat interface
      document.getElementById('chatBox').innerText = recognizedText;
    })
    .catch(error => {
      console.error('Error during OCR process:', error);
    });
}

// Example usage: When an image is selected/uploaded in the chat
document.getElementById('imageInput').addEventListener('change', (event) => {
  const imageFile = event.target.files[0];
  processImageForOCR(imageFile);
});
</script>

 

Explanation:

Filestack SDK Script: The <script src=”https://static.filestackapi.com/filestack-js/3.x.x/filestack.min.js”></script> tag is added to include the Filestack JavaScript SDK, which allows you to use the filestack.init() function in your JavaScript code.

Initialization: Initialize the Filestack client using your API key.

Upload Image: When an image is uploaded (e.g., through a file input in the chat application), it is uploaded to Filestack.

OCR Transformation: Once the image is uploaded, we apply the Filestack OCR transformation to recognize the text.

Output: The recognized text is then displayed in the chat interface or can be sent as a message.

Notes:

• In the OCR transformation, you can specify the language (language: ‘eng’) or use auto-detection for multiple languages depending on the use case.
• You’ll need to replace YOUR_API_KEY with your actual Filestack API key.

Translation services

Multi-language JavaScript OCR APIs are crucial in translation services. They quickly convert scanned documents, PDFs, or images with texts into editable and translatable formats. This allows translation platforms to process documents in numerous languages efficiently and deliver accurate results quickly. 

Here’s a simple code example demonstrating how to use Filestack Multi-Language JavaScript OCR API in a translation app. This example shows how to upload a scanned document, PDF, or image, recognize the text using OCR, and prepare it for translation:

<!-- Include the Filestack JavaScript SDK in your HTML file -->
<script src="https://static.filestackapi.com/filestack-js/3.x.x/filestack.min.js"></script>


// Initialize the Filestack client
const client = filestack.init('YOUR_API_KEY');

// Function to process the uploaded file and apply OCR
function processFileForTranslation(file) {
  // Upload the file to Filestack
  client.upload(file)
    .then(response => {
      // Get the file handle after upload
      const fileHandle = response.handle;

      // Apply OCR to extract text from the file
      return client.transform(fileHandle, {
        ocr: { language: 'auto' } // Auto-detect language or specify a specific language like 'eng'
      });
    })
    .then(ocrResult => {
      // Extract the recognized text
      const recognizedText = ocrResult.data.text;
      console.log('Extracted Text for Translation:', recognizedText);

      // Send the recognized text to a translation API (e.g., Google Translate API)
      translateText(recognizedText, 'en'); // Example: translating to English
    })
    .catch(error => {
      console.error('Error during OCR process:', error);
    });
}

// Function to translate the extracted text (using a mock translation API)
function translateText(text, targetLanguage) {
  // Placeholder for the translation API logic
  console.log(`Translating the following text to ${targetLanguage}:`, text);

  // Example: Make an API call to a translation service here (like Google Translate)
  // fetch(`https://translation.api/translate?text=${encodeURIComponent(text)}&target=${targetLanguage}`)
  //   .then(response => response.json())
  //   .then(translation => {
  //     console.log('Translation:', translation.translatedText);
  //     document.getElementById('translatedText').innerText = translation.translatedText;
  //   })
  //   .catch(error => {
  //     console.error('Translation error:', error);
  //   });
}

// Example: When a user uploads a document or image for translation
document.getElementById('fileInput').addEventListener('change', (event) => {
  const file = event.target.files[0];
  processFileForTranslation(file);
});

 

Explanation:

File Upload: The user uploads a scanned document, PDF, or image via an input file element. The file is then uploaded to Filestack.

OCR Transformation: After the upload, the Filestack OCR API recognizes the text from the document, image, or PDF. The language is set to ‘auto’ to automatically detect the language of the uploaded file.

Text Extraction: Once the OCR process is complete, the recognized text is extracted and logged.

Translation: The extracted text is sent to a translation API (in the example, it’s a placeholder function that would be replaced with an actual translation service, like Google Translate or another API). The result would then be displayed in the app or processed further.

Notes:

• The translateText function is a placeholder for where you would integrate an actual translation API.
• You can replace YOUR_API_KEY with your actual Filestack API key.
• You can modify the target language dynamically based on the user’s selection.
