ONNX.js Demo

ONNX.js demo is an interactive demo portal showing real use cases running ONNX.js runtime in VueJS. It currently supports four examples for you to quickly experience the power of ONNX.js runtime.

The demo is available here ONNX.js demo website.

NOTE: Currently, the supported platforms are Edge/Chrome/Firefox/Electron/Node.js (support for other platforms is coming soon).

Use Cases

The demo provides four scenarios based on four different ONNX pre-trained deep learning models.

1. SqueezeNet

SqueezeNet is a light-weight convolutional network for image classification. In the demo, you can select or upload an image and see which category it's from in miliseconds.

2. ResNet-50

ResNet-50 is a highly-accurate deep convolutional network for image classification. It is trained on 1000 pre-defined classes. Similar to the SqueezeNet demo, you can select or upload an image and see which category it's from.

3. FER+ Emotion Recognition

Emotion Ferplus is a deep convolutional neural network for emotion recognition in faces. In the demo, you can choose to either select an image with any human face or to start a webcam and see what emotion it's showing.

4. Yolo

Yolo is a real-time neural network for object detection. It can detect 20 different objects such as person, potted plant and chair. In the demo, you can choose to either select an image or start a webcam to see what objects are in it.

5. MNIST

MNIST is a convolutional neural network that predicts handwritten digits. In the demo, you can draw any number on the canvas and the model will tell you what number it is!

Run ONNX.js Demo

Install Dependencies

npm install

Serve the demo

Serve the demo in localhost

npm run serve

This will start a dev server and run ONNX.js demo on your localhost.

Deploy the demo

npm run build

This will pack the source files into /docs folder and be ready for deployment.

- Electron support

Onnx.js demo can also serve as a Windows desktop app using Electron.

First create a developer build of the app by running

npm run build -- --mode developer

Then run

npm run electron-packager

This will create a new /ONNXjs-demo-win32-x64 folder. Run /ONNXjs-demo-win32-x64/ONNXjs-demo.exe to enjoy Electron desktop app.
