Item tag processing system and method

A computer comprising:

• a processor;
• and
• a computer-readable medium coupled to the processor, the computer-readable medium comprising code executable by the processor for implementing a method comprising:
• receiving image data of an image of a shelf unit with specific items and item tags comprising machine readable codes adjacent to the specific items;
• identifying the item tags in the image data;
• identifying machine readable codes in one or more item tags in the image data;
• resizing the machine readable codes in the image data so that the machine readable codes are a same size;
• thresholding each pixel in the machine readable codes;
• after thresholding, performing a morphological operation on the machine readable codes;
• after performing the morphological operation, adjusting sizes of features of the machine readable codes;
• and
• after adjusting sizes, outputting modified machine readable codes.

A method comprising:

• receiving, by a server computer from a user device, image data of an image of a shelf unit with specific items and item tags comprising machine readable codes adjacent to the specific items;
• storing, by the server computer, the image data in an image database, wherein an image analysis computer obtains the image data from the image database, identifies the item tags in the image data, identifies machine readable codes in one or more item tags in the image data, thresholds each pixel in the machine readable codes, performs a morphological operation on the machine readable codes, adjusts sizes of features of the machine readable codes, determines modified machine readable codes, and stores the modified machine readable codes in an item information database;
• obtaining, by the server computer, the modified machine readable codes from the item information database;
• and
• updating, by the server computer, an application maintained by the server computer using the modified machine readable codes.
