Transformers.js

What is Transformers.js ?

Transformers.js is a JavaScript library designed to enable object detection in images. It leverages transformer-based architectures to provide accurate and efficient image analysis capabilities for web applications. The library allows developers to integrate state-of-the-art models into their projects seamlessly, making it easier to detect objects within images.

Features

• Object Detection: Identify and locate objects within images using pre-trained models.
• Image Analysis: Perform detailed analysis of image content for various applications.
• Integration with Popular Frameworks: Compatibility with frameworks like TensorFlow.js and browser-based environments.
• Customizable Models: Support for fine-tuning models to suit specific use cases.
• Cross-Platform Compatibility: Runs smoothly in both browser and Node.js environments.
• Efficient Performance: Optimized for fast inference and minimal resource usage.

How to use Transformers.js ?

1. Install Transformers.js: Use npm to install the package:

   npm install transformers.js  
   

2. Import the Library: Include the library in your JavaScript file:

   const {TransformerModel} = require('transformers.js');  
   

3. Load a Pre-trained Model: Initialize a pre-trained model for object detection:

   const model = new TransformerModel('object-detection');  
   

4. Preprocess the Image: Load and preprocess the image data for inference:

   const image = document.getElementById('image').files[0];  
   const tensor = model.preprocess(image);  
   

5. Run Inference: Perform object detection on the preprocessed image:

   const results = model.predict(tensor);  
   

6. Handle Results: Process the detection results to display bounding boxes or labels:

   model.postprocess(results).forEach(result => {  
     console.log(`Detected ${result.label} at ${result.coordinates}`);  
   });
