Do you want to extract it as a string? It is a difficult task, and you want to take a look at the Tools in the following toolboxes:
I doubt someone will post exactly how to do it, because it is a small project in itself. Have fun!

Have you tried OCR? Optical Character Recognition.
This comes with the Computer Vision System Toolbox.

This example would help - this is part of OCR example, but what it does first (- Step 4) is extracting the area of letters by removing other areas.
