Description

In this project, we develop an Android application that can translate signs from English to Chinese or other foreign languages with autovoicing.

In our application, the translation of the signs can be immediately performed by first placing the sign in the camera and then pressing the search button.

This application can be used for sign recognition at airports or on road, which helps foreigners to guide and enjoy themselves when traveling in the states without the hassle of opening a digital dictionary and typing in the text, and thus saving the trouble of making mistakes such as input typos. These functionalities can also be generalized potentially to cover guide translation at tourist attractions, menu translation at a restaurant, and text translation when reading a book. In addition, we implement all the computation in the cell phone using different commercial packages and saves the trouble of server communication.

 

We use the following libraries in our project :
