React Native / Expo image classification and object detection demos

Image Recognition and Object Detection with React Native/Expo

This React Native/Expo app demonstrates several pre-trained deep convolutional neural network models to classify images and detect objects on iOS and Android mobile devices.

---

Available Demos:

• Classify Image: image classification using TensorFlow.js w/ MobileNet model (on device - model will take a few seconds to initialize)

• Detect Objects: mutiple object detection using TensorFlow.js w/ COCO-SSD model (on device - model will take a few seconds to initialize)

• Food Detect: multiple food item detection using Clarifai Food model (remote API) *

To Run:

1. yarn install
2. yarn start (or expo start)

* To run the "Food Detect" demo, sign up for a free account at https://clarifai.com, obtain an API key, copy .env.example file to .env and add the API key. Make sure to verify your email address otherwise they will limit your account to 100 requests.
