A method for recognising articles to be processed, the method including the steps of: storing an indication of an expected set of repetitive processing of the articles, each article of the expected set being defined by a code compliant with a predefined coding, an offset from a representation of the code on the article, and a representation of a frame of predefined size representing a portion of the article at said offset from the representation of the code, repeating for each current article to be processed corresponding to an expected article of the expected set being defined by an expected code, an expected offset, and an expected frame: acquiring a current image representing at least part of the current article, searching the representation of a current code being compliant with the coding in the current image, a position in the current image of the representation of a corrupted code partially compliant with the coding being determined in response to a negative result of the search of the current code, extracting a current frame of said size from the current image at the expected offset from the position of the representation of the corrupted code, comparing the current frame with the expected frame, and determining a correctness of the article according to the comparison of the current frame with the expected frame. storing an indication of an expected set of repetitive processing of the articles, each article of the expected set being defined by a code compliant with a predefined coding, an offset from a representation of the code on the article, and a representation of a frame of predefined size representing a portion of the article at said offset from the representation of the code, repeating for each current article to be processed corresponding to an expected article of the expected set being defined by an expected code, an expected offset, and an expected frame: acquiring a current image representing at least part of the current article, searching the representation of a current code being compliant with the coding in the current image, a position in the current image of the representation of a corrupted code partially compliant with the coding being determined in response to a negative result of the search of the current code, extracting a current frame of said size from the current image at the expected offset from the position of the representation of the corrupted code, comparing the current frame with the expected frame, and determining a correctness of the article according to the comparison of the current frame with the expected frame. acquiring a current image representing at least part of the current article, searching the representation of a current code being compliant with the coding in the current image, a position in the current image of the representation of a corrupted code partially compliant with the coding being determined in response to a negative result of the search of the current code, extracting a current frame of said size from the current image at the expected offset from the position of the representation of the corrupted code, comparing the current frame with the expected frame, and determining a correctness of the article according to the comparison of the current frame with the expected frame.
