Transformers.js

What is Transformers.js ?

Transformers.js is a JavaScript library designed for object detection in images. It simplifies the integration of AI models into web applications, enabling developers to detect objects within images efficiently. The library is built to be user-friendly and accessible, even for those new to machine learning.

Features

• Real-time Object Detection: Transformers.js enables real-time object detection in images, making it suitable for applications requiring instant feedback. • Pre-trained Models: The library supports popular pre-trained models like YOLO, SSD, and Faster R-CNN, ensuring high accuracy out of the box. • Simple API: Transformers.js provides an intuitive API that allows developers to detect objects with just a few lines of code. • Hardware Acceleration: It leverages WebGL and WebGPU for hardware acceleration, ensuring fast performance even on less powerful devices. • Customizable: Developers can fine-tune models for specific use cases, such as detecting particular types of objects. • Cross-browser Support: The library works seamlessly across modern web browsers, ensuring wide compatibility.

How to use Transformers.js ?

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

   npm install transformers.js
   

2. Import the Library: Include Transformers.js in your JavaScript file:

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

3. Load the Model: Instantiate a pre-trained model:

   const model = new Transformer({
     model: 'yolov5s',
     weights: 'yolov5s.weights'
   });
   

4. Detect Objects: Pass an image element or URL to the model:

   const image = document.getElementById('image');
   model.detect(image).then(results => {
     console.log(results); // Array of detected objects with bounding boxes and labels
   });
   

5. Handle Results: Process the detection results to display bounding boxes or labels on the image.
