Ever come across a street sign, menu, or document in a foreign language and wished it could magically switch to one you understood? That’s exactly what image translation solves.

Unlike traditional translation tools that only work on typed text, image translation detects and translates embedded text in real-world images, preserving both the meaning and visual design.

Today, we'll explore the challenges of image translation, how we tackle this problem, and how you can implement this capability in your applications using our translation model.

The Challenge of Translating Text in Images

Translating text within images is considerably more complex than standard text translation for several reasons:

1. Text Detection and Extraction: Unlike plain text, systems must first identify where text appears within an image, handling various fonts, sizes, orientations, and backgrounds.

2. Visual Context Preservation: After translation, the text needs to be reintegrated into the original image while preserving visual context, maintaining the original styling, and ensuring it looks natural.

3. Handling Complex Backgrounds: Text often appears over varied backgrounds, making clean extraction and replacement challenging.

Traditional OCR (Optical Character Recognition) tools can extract text, but typically don't handle the complete end-to-end process required for high-quality image translation.

How JigsawStack Solves Image Translation

Our approach to image translation involves a sophisticated multi-step pipeline combining computer vision, machine learning, and natural language processing:

Step 1: Visual OCR

Our vOCR model identifies every piece of text in the image with bounding boxes, orientation, and confidence scores.

Step 2: Inpainting

We remove the original text while preserving background texture using advanced inpainting models.

Step 3: Translation

The extracted text is translated to your target language using out translation model, while maintaining nuance and context.

Step 4: Text Reintegration

We match the font, style, color, and position, so the translated image still looks like the original.

Use Cases and Applications

Image translation has numerous practical applications:

• Travel and Tourism: Instantly translate signs, menus, and maps while traveling

• E-commerce: Make product images with foreign text accessible to global audiences

• Education: Translate educational materials, diagrams, and infographics

• Content Localization: Efficiently localize marketing materials, advertisements, and social media content

• Document Processing: Translate visual elements in documents while maintaining layout integrity

• Research: Access and understand foreign research materials with visual elements

How to Use JigsawStack's Image Translation Model

Our API makes it easy to implement image translation in your application. Here's a simple example using JavaScript:

Results:

Our API supports two main methods for providing input images:

1. URL - Simply provide a link to the image online (as showcased above).

2. File Store Key - Reference a previously uploaded image in our storage system

3. Blob (or) Buffer - You can pass the image directly to our API.

You can also customize the translation process with optional parameters:

Future Enhancements

We're continuously improving our image translation capabilities and also cooking a native image generation model to enable the same task ;). Current development areas for this version include:

• Enhanced Font Matching: More precise font detection and matching for even more natural results

• Improved Erasure Models: Research into better inpainting technologies for challenging backgrounds

• Style Preservation: Better preservation of text styles, colors, and effects

• Layout Understanding: Deeper comprehension of document layouts and text relationships

• Expanded Language Support: Adding more language pairs with specialized handling for different writing systems

Conclusion

JigsawStack's Image Translation model represents marks a step forward in breaking down language barriers in visual content. By combining advanced computer vision, machine learning, and translation technology, we've created a solution that can transform how people and businesses interact with foreign language content.
