ABSTRACT

From the past days man is inventing various things to lead a comfortable & luxurious life. Not only inventing newer things but also he is continuously attempting to implement new technologies into that field. In this attempt he got success in finding out a computer, which can be undoubtedly called, his fantasy.

After invention of the revolutionary devices like the computer, most of us still use pen and paper for any information interchange. Typing, for the most part, is reserved for final productions. For quick notes, drafts, and ideas it is easier to jot them down on paper. This is a project based on Image processing technique, to have a digital copy of everything written on paper without the need of special papers or a scanner.

With the image processing technique, everything (i.e., alpha-numeric data) you write down on paper will now also show up on the computer screen. Best of all, it will work with any paper up to letter (A4) size. Here the concept is to capture the image of some specific area and from that captured image; the characters are extracted using optical character recognition technique which is implemented in Matlab. The extracted characters are displayed on the computer screen.

Applications:

· Mobile Phone

· PDA’s

· Digital Accessories

Advantages:

· Useful for quick information interchange

· Eliminates time wastage in making soft copy from hard copy

· Simple and easy to operate

Technologies:

· Digital Camera

· Image processing techniques

· MATLAB

OUTPUT:

CONCLUSION:

The concept has been implemented successfully. The module is working perfectly. Different concepts in the digital image processing and the basic programming of the MATLAB have been studied. The alpha-numeric data which is written on the paper is successfully displayed on the computer screen in standard text format.

Since many threshold mismatching occur causing more delay, only a few lower case letters have been included. But as the concept is same, we can extend it to the rest of letters and special symbols. As MATLAB is the interfacing software the output is not as fast as expected. A delay has been maintained to avoid any misconceptions.

FUTURE SCOPE:
As we have successfully worked out our concept on alpha-numeric data, there is a scope for extending it to the other special symbols.

On further research, our project can be presented in its more advanced version where there is no need for writing manually. We just need to virtually scribble with our fingertip without using any pen and paper. As we move our fingertip the path is traced and the scribbled data is displayed on the GUI of the computer.
