How can i detect moving robot in an image and find its pixel value(coordinate value)

We are tracking robot and find its position by overhead camera .We have marked black square on top of robot.We want to find pixel coordinate value of Center of Square.

If You Have any Other Suggestion(or Methods) for Tracking The Robot By an Overhead Camera Input.

This is not an image taken overhead by your camera. Why did you not post the actual image?

[harjeet singh]

actual image is totally different than what you made by yourself, that will have full of noise.

See my Image Processing Tutorial: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862

It will show you how you can threshold an image to find light or dark things (like the square on your robot) and determine the centroid location of the thing(s).
