This is a simple image classifier using TensorFlow.js. It accesses the feed through the webcam and you can save various objects/gestures into classes so that you can classify them later. Each time you click one of the "Add" buttons, one image is added to that class as a training example. While you do this, the model continues to make predictions on webcam images coming in and shows the results in real-time.
This image classifier was created by following the Google TensorFlow.js Image Classifier Tutorial and added some bootstrap to make the app responsive.
