1. A system for extracting a region of interest from a captured image of an item, the system comprising:
an imaging device configured to capture an image of an item, the captured image comprising a computer readable code region; and
a processor in data communication with the imaging device and configured to:
convert the captured image of the item into a plurality of sets of digital data forming a first matrix, the first matrix being represented by combined first digital values and second digital values;
identify a first pixel region in the plurality of sets of digital data, the first pixel region comprising:
one or more second matrixes, each second matrix being smaller than the first matrix, each second matrix comprising two or more consecutive rows of combined first digital values and second digital values having the same arrangement;
determine the identified first pixel region as the computer readable code region;
define a region of the plurality of sets of digital data excluding the first pixel region as a second pixel region;
remove the second pixel region from the plurality of sets of digital data; and
store or process only the first pixel region.
