How to Use Tesseract OCR as an Assist for Barcode Scan

When scanning barcodes, the recognition rate is affected by image quality. If a barcode image is severely damaged, the barcode algorithm may fail to work. Fortunately, most of the linear barcodes (1D barcode) are printed with corresponding texts. OCR (optical character recognition) algorithm could be a complement to the barcode algorithm in such a scenario. In this article, I will share how to use Tesseract OCR to boost the barcode scan.
