Barcode Photo-image Processing System

A computer implemented system for processing a captured image of a barcode, said computer implemented system comprising:

• at least one processor;
• a non-transitory computer readable storage medium communicatively coupled to said at least one processor, said non-transitory computer readable storage medium storing modules of an image processing application of said computer implemented system that are executable by said at least one processor, said image processing application comprising:
• an image acquisition module that acquires said captured image of said barcode, wherein said barcode is of a plurality of types and comprises a large amount of data, and wherein said captured image of said barcode is of low quality;
• a barcode type determination module that determines a type of said barcode in said acquired image of said barcode;
• a gray barcode creation module that creates a gray barcode image from said acquired image of said barcode, by gray shading over an entirety of said acquired image of said barcode;
• a modularization module that modularizes said created gray barcode image based on said determined type of said barcode;
• and
• a binarization module that binarizes said created gray barcode image based on said determined type of said barcode by one of comparing an average gray level intensity of each of a plurality of grids of pixels in said created gray barcode image and comparing a gray level intensity of each of individual pixels in said created gray barcode image, with a predetermined threshold.

A computer program product comprising a non-transitory computer readable storage medium, said non-transitory computer readable storage medium storing computer program codes comprising instructions executable by at least one processor, said computer program codes comprising:

• a first computer program code for acquiring a captured image of a barcode, wherein said barcode is of a plurality of types and comprises a large amount of data, and wherein said captured image of said barcode is of low quality;
• a second computer program code for determining a type of said barcode in said acquired image of said barcode;
• a third computer program code for creating a gray barcode image from said acquired image of said barcode, by gray shading over an entirety of said acquired image of said barcode;
• a fourth computer program code for modularizing said created gray barcode image based on said determined type of said barcode;
• and
• a fifth computer program code for binarizing said created gray barcode image based on said determined type of said barcode by comparing one of a computed average gray level intensity of each of a plurality of grids of pixels in said created gray barcode image and a computed gray level intensity of each of said pixels in said created gray barcode image with said predetermined threshold depending on said determined type of said barcode.
