In this mini-project I describe a classification interface developed by me, using some very famous classification schemes. The interface can be used for hand-written numbers between 0 and 9. It employs the use of three classification algorithms (refer references).
Disclaimer - I do not own any of these algorithms and have simply implemented them using MATLAB.
