Barcode library or Barcode SDK is a software library that can be used to add barcode features to desktop, web, mobile or embedded applications. Barcode library presents sets of subroutines or objects which allow to create barcode images and put them on surfaces or recognize machine-encoded text / data from scanned or captured by camera images with embedded barcodes.
This comparison of optical character recognition software includes: . OCR engines, that do the actual character identification; Layout analysis software, that divide scanned documents into zones suitable for OCR
ZBar is an open-source C barcode reading library with C++, Python, [2] Perl, and Ruby bindings. [3] [4] [5] It is also implemented on Linux and Microsoft Windows as a command-line application, [6] and as an iPhone application.
The platform incorporates the enterprise-grade barcode scanning and text recognition software library (SDK) base product, driven by proprietary computer vision algorithms. The SDK can be integrated into third-party apps, allowing any smart device with a camera, such as smartphones, to become a mobile barcode scanner.
Asprise OCR is a commercial optical character recognition and barcode recognition SDK library that provides an API to recognize text as well as barcodes from images (in formats like JPEG, PNG, TIFF, PDF, etc.) and output in formats like plain text, XML and searchable PDF. Asprise OCR has been in active development since 1997.
The longer the barcode is, the greater distance of laser barcode reader from barcode image is needed, making reading difficult or impossible above some threshold lengths/distances. The optimal encoding can be found using a dynamic programming algorithm.
A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and ...
An example of a High Capacity Color Barcode: a Microsoft Tag referring to the HCCB article on the English Wikipedia. High Capacity Color Barcode (HCCB) is a technology developed by Microsoft for encoding data in a 2D "barcode" using clusters of colored triangles instead of the square pixels conventionally associated with 2D barcodes or QR codes.
