I am using matlab version 7.10.0.499 (R2010a). I am taking input as .jpg file to imread function, I am getting the pixel coordinates. I need a function which can convert pixel coordinate to Cartesian x-coordinate and y-coordinate. A=imread('file.jpg'); How to convert value present in A matrix into Cartesian x-coordinate and y-coordinate.

That would be returning the 'xdata' and 'ydata' properties from the figure. See
doc get % and set and friends
doc axes % for axes properties

See my attached spatial calibration demo to convert pixels into real world distances.
