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.

Wrapping C++ OCR Library in Java

Dynamsoft OCR SDK is totally implemented in C++, which means it is easy to be wrapped in high-level programming languages, such as C#, Java, Python and so on. As a proprietary development SDK, so far, only .NET OCR library is available for commercial use. Because some of developers and users are hoping that Dynamsoft could provide a Java OCR library, I wrapped the C++ OCR library for test. Anyone can feel free to use the sample, and I’d like to receive feedbacks from you.

Online OCR – Convert Images to Word, Text and PDF

Last time, I wrote an article Free Online OCR Service with Dynamsoft TWAIN SDKs, which introduced how to create an online OCR application with Dynamic .NET TWAIN SDK step by step. Since then, I have received some feedbacks about how to convert the OCR results to Microsoft Office documents. So today, I’d like to share how to utilize Open XML SDK to convert OCR results to word document. Based on the sample code I shared last time, I’ll make a little bit of change.
