1. A system for processing items, the system comprising:
a reader configured to capture an image of an item, the item comprising a computer readable code and additional item information positioned thereon, the additional item information spaced apart and different from the computer readable code; and
one or more processors in data communication with the reader and configured to:
obtain a captured image of the item, the captured image including the computer readable code, the computer readable code storing retrievable information associated with the item;
downconvert the captured image to generate a downconverted image of the item, the downconverted image being smaller in size than the captured image;
detect an edge of the computer readable code in the downconverted image;
identify a region of the computer readable code in the downconverted image, comprising images of the computer readable code and the additional item information, based at least in part on the detected edge of the computer readable code in the downconverted image; and
store or process only the identified region of the computer readable code such that the additional item information is not stored or processed.
