You have got the pixel in your pic. Now you need a calibration scale, something like 1 feet are 1200 Pixels (for instance).

thanks Valentino.. What about the accuracy? how much percentage we will get accuracy on an average?

Matlab doesn't lose any of the pixels in your picture. If you put in an exact calibration scale, you'll only have the accuracy error from your resolution. If you cannot provide an exact calibration scale, that will also put down your accuracy.
