Transformers.js

What is Transformers.js ?

Transformers.js is a JavaScript library designed for object detection tasks. Built on top of the popular Transformers library by Hugging Face, it allows developers to integrate state-of-the-art models into web applications. The library simplifies the process of loading models, preprocessing inputs, and making predictions directly in the browser. Transformers.js is ideal for identifying and classifying objects within images efficiently.

Features

• Model Loading: Easily load pre-trained models from the Hugging Face Model Hub.
• Inference in Browser: Run object detection models directly in the browser without backend setup.
• Integration: Works seamlessly with TensorFlow.js and other popular frontend libraries.
• Extensible: Customize workflows with built-in hooks for preprocessing, postprocessing, and data augmentation.
• Browser Support: Compatible with modern browsers, enabling deployment across various platforms.

How to use Transformers.js ?

1. Install the Library: Use npm to install Transformers.js in your project:

   npm install @huggingface/transformers  
   

2. Import and Load Model: Import the library and load a pre-trained model:

   const { AutoFeatureExtractor, AutoModel } = require('@huggingface/transformers');  
   const model = await AutoModel.load('facebook-detr-resnet-50');  
   const featureExtractor = await AutoFeatureExtractor.load('facebook-detr-resnet-50');  
   

3. Preprocess Image: Convert your image input using the feature extractor:

   const inputs = await featureExtractor.close(true);  
   

4. Run Inference: Apply the model to generate predictions:

   const outputs = model.predict(inputs);  
   

5. Handle Results: Extract bounding boxes, class labels, and confidence scores from the outputs:

   const result = await outputs.print();  
   console.log(result);
