Digital ink recognition Server

This program turns your Android device or Android emulator to Handwriting recognition server.

Server implements REST API, accepts handwriting data in JSON format and returns result (recognized text) in JSON format. Text recognition happens directly on Android device. At first request to server, server downloads (model) data from the internet used to recognize handwriting.
