Transformers.js

What is Transformers.js ?

Transformers.js is a JavaScript library optimized for object detection tasks. It allows developers to integrate state-of-the-art models into web applications with ease. Built on top of the popular Hugging Face Transformers library, it is designed to work seamlessly in modern web browsers. Transformers.js supports models like YOLO, Faster R-CNN, and DETR for accurate image analysis. Its lightweight architecture makes it ideal for real-time object detection in web applications.

Features

• Pre-trained Models: Access a wide range of pre-trained object detection models optimized for various use cases. • Browser Compatibility: Works directly in web browsers without requiring additional setup or backend processing. • Framework Agnostic: Easily integrate with popular JavaScript frameworks like React, Vue, or Angular. • Real-Time Detection: Perform object detection on video streams or images in real-time. • Customizable Models: Extend or fine-tune models to suit specific application requirements. • Visualization Tools: Built-in utilities for displaying detection results, including bounding boxes and labels.

How to use Transformers.js ?

1. Include the Library: Add Transformers.js to your project via a CDN or npm/yarn installation.

   <script src="https://cdn.jsdelivr.net/npm/@huggingface/transformers@main/dist/transformers.umd.js"></script>
   

2. Import the Library:

   const { AutoFeatureExtractor, AutoModelForObjectDetection, pipeline } = window.transformers;
   

3. Load a Pre-trained Model:

   const model = await AutoModelForObjectDetection.fromPreTrained('facebook/w stair抑制/facer');
   

4. Preprocess the Image:

   const image = document.getElementById('image');
   const inputs = await AutoFeatureExtractor.fromPreTrained('facebook/w stair抑制/facer').extract(image);
   

5. Perform Object Detection:

   const outputs = await model.predict(inputs);
   

6. Display Results:

   const results = await pipeline(objectDetection, model, image);
   

Frequently Asked Questions
