Improvement in two-dimensional barcode

Abstract

Barcode is one of the existing systems which is very fast in scanning and more accurate when compared with other coding systems. It is extensively used because speed of scanning the barcode is very high as compared with manual data entry. To increase the capacity of 2D monochrome QR code to 3 fold, 2D colour QR code is developed. The challenge in the development of colour barcode is in its decoding, since the intensity and depth of colours vary during the printing and scanning process. We need to understand the decoding process and make it insensitive to such variations. A lot of work has been already done to deal with such variations but acceptable results have not yet been achieved. The objective behind colour barcode is to increase the capacity to 3 fold as compared with 2D monochrome barcode. In this paper we proposed a novel approach that will increase the capacity of barcode beyond 3 fold and deals with decoding problem of intensity variation. In the proposed technique, quantization of grey levels is specified to handle the problem of intensity variation.

“…They also proposed a binarization and grouping algorithm to encode data to form a color barcode [20]. Wasule and Metkar took into account the intensity variation which occurs while decoding colored barcodes and proposed an approach that will increase the capacity of barcodes beyond threefold; in their work, they used quantization of grey levels [59]. Ramalho et al used the concept of super-modules to encode more data into QR-Code but also to make QR-Code more secure [42].…”

Ventajas del uso de sistemas de trazabilidad electrónica en procesos de manufactura

“…Uno de los sistemas de trazabilidad más utilizados es el código de barras, utilizado en cualquier tipo de sociedad, industria o mercado (Rădulescu y Popescu, 2014), esto gracias a su rapidez para escanear productos en comparación con otros sistemas, además de la gran velocidad de captura de información y su creciente popularidad en distintos sectores (Wasule y Metkar, 2017). Un sistema por código de barras le permite al usuario identificar productos, de manera automática e inequívoca; se utiliza para identificar números de productos, números seriales y números de lote.…”

Review of traceability system applications. Case study: the wiring harness industry

“…One of the most widely used traceability technologies is the barcode, due to its rapid scanning speed, accuracy and high-speed capturing of information, when compared to manual data capture (Wasule & Metkar, 2017). This technology is employed in multiple industries and markets (Rădulescu & Popescu, 2014), since it can capture information automatically and unequivocally (Correa et al, 2010).…”
