Abstract: A method includes identifying a set of functional parameters that are settable for processing the image and a plurality of instances of the set of functional parameters. A different mode for processing this image corresponds to each of these instances. The method includes selecting a determined processing mode for decoding the optical information from the processing modes of a working set of processing modes, and applying this selected processing mode and further comprises associating with each processing mode a respective probability of success. Selecting one of the methods of the working set includes choosing the processing mode with the highest value of probability of success and updating after each application of the selected processing mode, both if the decoding was successful and if the decoding was not successful, the probability of success of each processing mode of the working set, such as to perform adaptive decoding of the optical information.

Abstract: A method for decoding a two-dimensional optical code formed by a set number of codewords, wherein decoding the code based on a single acquired image has not been successful, includes analyzing an acquired image and at least one further acquired image and obtaining a respective set and further set of values of identified codewords. Each codeword can take on either an undefined value or vice versa a numeric value if the codeword is recognized. A combined set of codewords is created and each codeword of the combined set is assigned a value of a codeword of the set and/or of the further set and an algorithm for detecting and self-correction of errors is applied to the combined set to obtain confirmation of successful decoding of the two-dimensional code.
