Abstract: Methods and apparatus for detecting labels included in a document or other binarized image, and for extracting and/or using information associated with a label, are described. A nodal structure modeling objects, e.g., characters, character strings or words, which make up various label aliases are described. The nodal structure is used to generate a score for portions of a binarized document with the scores being used to determine the presence or absence of one or more label aliases. When a label alias is determined to be present, information is extracted from the document and used as information corresponding to a label to which the identified label alias corresponds. Multiple different label aliases may correspond to a single label allowing multiple different aliases to be used to identify the same information. The label aliases and information extraction can be and sometimes used to extract information from scanned forms.

Abstract: Systems and methods of operation thereof for identifying containers handled by a container handling apparatus. Each container has a portion that includes one of a plurality of identifying patterns. A camera generates an image of at least the portion of the container including the identifying pattern wherein the image includes a pattern image corresponding to the identifying pattern. An image processor detects an optical characteristic of the image within a defined region of the image and detects the pattern image as a function of the detected characteristic. The defined region of the image includes the pattern image corresponding to the identifying pattern. The image processor determines the container's identifying pattern as a function of the pattern image detected by the image processor thereby to identify the container.
