Handwritten Digits Recognition Using Google Prediction API ?

This project is just ... for fun. The image used in this project was acquired from OpenCV sample folder (opencv/samples/python2/data/digits.png), thus it's not included here.

Dependencies:

Python 2.7, Google App Engine, Google API Python Client, OpenCV, NumPy

How to run:

  1. 'prepare_data.py' This will generate training data in cvs format and testing data in txt format. Training data contains 2500 digits (0 - 9), 250 for each. There are 10 txt files for testing purposes, each contains one sample.

  2. 'train.py' Before training, create your client ID as a installed application type, and place your 'client_secrets.json' file in the same folder. The prediction API will create a classification model.

  3. 'predict.py' Choose any txt file in 'test_data' folder and make prediction. The result is shown in both bar and pie charts.
