1. An image processing method comprising:
obtaining an image comprising an encoded signal therein;
analyzing the image to determine an encoding techniques used to encode the encoded signal therein;
grouping associated encoded image areas within a bin associated with a determined encoding technique;
selecting at least one encoded image area from the bin as a test image area, wherein the test image area is to be used to determine encoded signal robustness for a printed version of the image.
