Abstract: A system and method for processing imaged machine readable indicia may include capturing an image of a machine readable indicia including multiple codewords. A determination of an actual scanline of a codeword of the captured indicia may be made. A virtual scanline of the codeword of the imaged indicia for a type of symbology may be generated. In response to the virtual and actual scanlines matching, data representative of the codeword may be stored. Otherwise, repeat generating virtual scanlines of the codewords and compare the generated virtual scanlines with the actual scanlines until a match is identified or possible virtual codewords are exhausted. In response to a match, data representative of the matched scanline may be stored. The process may further repeatedly determine, generate, and compare until each codeword is determined. Data represented by the indicia based on the stored data representative of the matched codewords may be generated.

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 barcode decoding method includes obtaining a plurality of scanning lines defining a second set of scanning lines which also comprises a predetermined scanning line. Each scanning line has a first set of pixels, each identified by a first and by a second index. The pixels that are part of the second set of scanning lines define a third set of pixels and, from the pixels of the third set of pixels, it is possible to select a fourth set of pixels to construct an oversampled profile of the barcode, ordering intensity values calculated from the intensity values of the pixels of the fourth set. The pixels of the fourth set include pixels of the predetermined scanning line and further pixels of the third set that do not belong to the predetermined scanning line, to obtain a subpixel resolution that is able to decode the barcode.

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.
