This paper describes a machine learning approach for visual object detection which is capable of processing images extremely rapidly and achieving high detection rates.

KeywordsMultiple symbology-1D/2D barcode segmentation-background clutter elimination-barcode verification-automatic barcode extraction Experimental results indicate that the proposed approachĬan segment multiple barcodes from the complex background with acceptable accuracy. Operation, connected component labeling and iterative thresholding. The whole algorithm combines several image processing methods, namely, image subtraction, Gaussian smoothing filtering, morphological The proposedĪlgorithm has three main steps: background small clutters elimination, potential barcodes segmentation and barcode verification. When multiple types of symbology appear in the same snapshot for 1D barcodes, 2D barcodes, or both co-exist. Extended from our preliminary investigation and for realisticĬonsideration, this work proposes a general segmentation framework to achieve extraction of real barcodes under complex background Multi-symbologyīarcode extraction is a practical issue and yet challenging issue. Methods discussed in literature may either work for single 1D/2D barcode or rely on finding the unique finder pattern. Image-based barcode recognition technique is a robust and extendable approach for versatile 1D/2D barcodes reading. The results of testing our system show that the system can provide useful services for consumers and satisfies their needs. Also, the system includes web services "User web page" to facilitate user access to online profiles for editing accounts, and subscribing to other services. Results are related to whether users can eat or drink the product based on user preferences and needs such as religion (no meat, beef, pork, or wine), or health settings such as allergies, chronic diseases or calories. The system consists of mobile-phone J2ME based side to scan product barcodes, recognize it, submit user inquiries to a server, and display results. People can use the system to easily buy products that fit with their preferences and needs.

Consumers can use the mobile built-in camera to scan a barcode that presents on virtually every product world-wide, then middleware and communication technologies are used to recognize the barcode and access product-related information.īecause the creation of such mobile phone based applications that provide services and information to real-world objects is currently very attractive, we propose an innovative software system called "EZBuy: My Product Info" that makes use of modern middleware technologies and available hardware and communication systems.

These applications can facilitate people shopping and improve life quality. These technologies integrated with barcode systems assist developing mobile-phone based barcode recognition applications. With the steady growth and affordability of camera phones, available hardware and communication systems, and modern middleware technologies, more necessary mobile applications have become possible.

The system has been effectively deployed for the decoding of PDF 417 codes on student university cards at the university.

In order to reduce the algorithm complexity further, different techniques have been devised on hardware level such as light conditioning and orientation, placement of barcode and distance from the camera. Additionally, they got the capability to run the complex image processing algorithms on application level, which increases the prototyping speed considerably for 2D barcode implementation.

On the other hand, modern android mobile/tablets are ready to use hardware platform that fulfills all the essential hardware requirements to implement the extraction of barcodes.

These modules are complex in their design and also take considerable amount of time for their development, testing and verification both at software and hardware levels. Dedicated Hardware for two dimensional (2D) barcodes is used in numerous applications depending on the levels of preserving data in complex format.
