How to identify symbols in a image

I have a image which contains GUI components such as Button, Label, ComboBox, CheckBox etc. I want to write a Java program to process this image and identify each components and their positions, height and width. Is it possible? If possible, how should I do?

Thanks;开发者_C百科

I would suggest looking at javacv, the java binding for opencv.
