This document discusses using IBM Watson's visual recognition service to build a mobile app called Recycletor that can identify whether garbage items are recyclable or not. It provides steps to create a visual recognition service on IBM Bluemix and train a custom classifier. The document demonstrates how to test the API using sample images and Postman. It also shows how to integrate the visual recognition API into a simple Android app to allow users to take pictures of garbage and receive feedback on whether each item can be recycled. The goal is to make it easy for people to identify recyclable materials in their environment.
