METHOD OF DECODING OPTICAL INFORMATION

摘要

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.

1. A method for decoding optical information present in an acquired image, and comprising:
identifying a set of functional parameters that are settable for processing said image and a plurality of instances of said set of functional parameters, and in which each of said instances corresponds to a different processing mode for said image; selecting a processing mode for decoding said optical information from the processing modes of a working set of processing modes; and applying said selected processing mode; associating with each processing mode a respective probability of success; wherein said selecting a processing mode comprises:
choosing the processing mode with a highest probability of success value;updating after said applying said selected processing mode, both if said decoding was successful and if said decoding was not successful, a probability of success of each processing mode of said working set, such as to provide adaptive decoding of said optical information.
