Abstract: A computing device for extracting target data from a source document includes: a memory storing target data extraction rules; a processor connected with the memory, the processor configured to: obtain text recognition data extracted from an image of the source document, the text recognition data indicating locations of text structures in the source document; define text lines based on the text recognition data; identify a reference string from the text recognition data; select a subset of the text lines based on a location of the reference string and the target data extraction rules; and output the subset of the text lines as the target data.

Abstract: Methods and apparatus to determine barcode decoding parameters for a plurality of barcodes in an image are disclosed. An example method includes: obtaining image data representing an image including a plurality of barcodes; decoding a first barcode of the plurality of barcodes from the image data; determining a set of barcode decoding parameters used to successfully decode the first barcode; determining whether the plurality of barcodes encoded using at least one of a same barcode size, a same module size, or a same barcode format; and when the plurality of barcodes are encoded using at least one of the same barcode size, the same module size, or the same barcode format, attempting to decode all remaining barcodes of the plurality of barcodes from the image data using first the set of barcode decoding parameters.

Abstract: Embodiments of the present invention generally relate to the field of inventory management. In an embodiment, the present application is a method of reading barcodes. The method includes capturing, by an imaging assembly, an image of a target, the target including: (i) a symbol encoding a payload data, and (ii) a set of one or more alphanumeric characters containing a payload descriptor associated with the symbol; decoding, by a first processor, the symbol to extract the payload data; performing, by a second processor, an optical character recognition analysis on the set of one or more alphanumeric characters to identify the payload descriptor associated with the symbol; associating the payload data with the payload descriptor, resulting in an associated pair; and forwarding the associated pair to a third processor for further processing of the payload data based on the payload descriptor.
