Mobile phone translator application

Abstract

Mobile phone translator application is used to capture images of any text and make all the required image processing phases until getting a thresholded image of characters , then stating to extract letters and get features for these letter, the last phase is comparing these features with already existent database of letters and their corresponding features , and outputs the best matching letter and formulate the word in a text and translates it to any languages. The application is developed for android phones on platform 2.3.3 , API 10, tesseract library is used version 3 , mostly in the preprocessing phase. SQL ite is used for the building the database required. The first phase of the project is to handle getting an image either by capturing an image by the mobile camera, or browsing the gallery for an existent image on the phone. Applying all the required pre-image processing functions from conversion to grayscale, then removing the noise with filter , convert the captured image to threshold image, then using tess-two library to find words and characters segmentation, then surrounding these letter with a bounding rectangle to be able to extract each letter.
