Transformers.js

What is Transformers.js ?

Transformers.js is a JavaScript library designed for detecting objects in images on the client side. It leverages modern machine learning models to enable accurate and efficient object detection directly in web browsers. The library provides an intuitive API for developers to integrate object detection capabilities into their web applications without requiring server-side processing.

Features

• Real-time Object Detection: Detect objects in images or video streams with low latency.
• Pre-trained Models: Ships with models like SSD MobileNet and others for accurate detection.
• Selfie Segmentation: Includes models for segmenting people from the background.
• Customizable: Supports using custom models for specific detection tasks.
• Browser Compatibility: Works in modern browsers without requiring additional plugins.
• API Access: Provides a clean JavaScript API for easy integration into web applications.
• Integration Ready: Compatible with popular front-end frameworks like React, Angular, and Vue.js.

How to use Transformers.js ?

1. Install the Library: Include Transformers.js in your project via npm or CDN.

   npm install transformers.js
   

2. Initialize the Detector: Load a pre-trained model for object detection.

   const detector = new Transformers.Detector('ssd_mobilenet_v2');
   

3. Process an Image: Pass an image or video element to the detector.

   const image = document.getElementById('inputImage');
   const results = await detector.detect(image);
   

4. Handle Results: Use the detected objects in your application.

   results.forEach(result => {
     console.log(`Detected ${result.label} at (${result.x}, ${result.y})`);
   });
