Abstract
The invention relates to a method and device for detecting and decoding a two-dimensional encoded pattern, e.g. of the Robust Encoding Pattern type (REP), even in case the pattern is applied on a non-uniform colored background of a surface of a substrate. The operations for decoding such an encoded pattern involve detecting the states of its symbols through a test pattern, checking that local differences between parameter values of the elements of the symbols are consistent with an allowed representation of the test pattern to assign via a one-to-one mapping the states of the symbols of the test pattern to the corresponding symbols of the encoded pattern, and decoding the encoded pattern based on the assigned representation of its symbols.
