Image processing is the one of the most recent technology that has a very wide important in the application level. Image processing as well as digital signal processing has a wonderful future in building the real time application. It can introduce new level of application software. It can create a wonderful world of interacting devices. It can be used in producing user friendly & reliable instruments. Measurement devices and equipments are just possible by processing the signals in real time.
Here we are using a development platform, which is MATLAB. The MATLAB® desktop tools and development environment help you use MATLAB functions and files. MATLAB is an interactive system whose basic data element is an array that does not require dimensioning. This allows you to solve many technical computing problems, especially those with matrix and vector formulations, in a fraction of the time it would take to write a program in a scalar non interactive language such as C or Fortran. MATLAB has evolved over a period of years with input from many users. In university environments, it is the standard instructional tool for introductory and advanced courses in mathematics, engineering, and science. In industry, MATLAB is the tool of choice for high-productivity research, development, and analysis
In this project “WHEEL CHAIR CONTROL USING EYE-TRACKING” we developed, the motion of the pupil of the eye is tracked and commands are issued to the wheel chair system to move. The digital image signals are fetched from peripheral device and are sending to the computer using I/O ports. The processing is done in system itself in real time and the output is send through the I/O ports to do the rest of the job. Here we incorporate a low level microcontroller based system to carry out the final steps. Hence the project is a combination of high level programming with the low level embedded programming.
Here we use a PIC 16F877 based motion controller. It is connected to a basic relay circuit to control the movement of DC motor which is actually connected to the Wheels of Wheel Chair. Basically any one can control the movement of wheel chair using their eyes. And this project is aimed for developing such a wheel chair especially for disabled and old aged people. It is user friendly and most reliable interactive device.

The rainbow formed just after a rain. You can see the kholli hills in the background.
The evening sky. I took this pic when i was standing on the roof of our building.
3624 steps which is leading to the waterfall in kholli hills. see the waterfall below. i counted it when we returned. Because it took much time.. and effort. just i dont want to miss the credit !
It was still raining in there when we reached the waterfall point. It look like we were in jurassic park or amazon. Thick forest with slipery rocks, mountains, giant trees..... the journy was really an adventures. Monkeys and other creatures... and trenches to one side.
to reach the bottom, it was a dangerous move. water flowing full speed pushes us back to where we start. Wind blowing at more than 40 km/h. water was around 18 digree. i should say i cant express the feeling using my words. U should love this... if u love adventure !! this was a real hiking.... a wonderful experiance
