How to recognize blurry bar code image?


enter image description here This is my bar code image. I can not scan the code information use zbar or zxing. Are there any image processing or computer vision method which can make this be recognized?


Solution

  • You can try blind or supervised deblurring methods such as Lucy-Richardson deconvolution. This seems to be an EAN128, and blur information can be extracted from the known bars (EAN signature).

    Or try advanced methods such as in https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2898212/ (and cited articles).

    But honestly, chances are fairly low.
