Barcode Detection

Modern mobile phones or smartphones have multipurpose functions apart from being used as a device for voice and text communications. They are also embedded with many useful sensors, including camera, barometer, ac-celerometer, and digital compass. Unlike other types of sensor, the smartphone camera has been underutilized. This paper aims to fill the gap by analyzing and reviewing the hardware and software components of smartphones and highlighting the potential uses of the smartphone camera to support human daily life activities. A simple search of research papers indexed in Google Scholar was carried out using guided terms. The papers were filtered to match the research questions for this study. Only relevant papers were analyzed and reviewed. The results of the analysis suggested that the rapid development in the smartphone hardware has extended the use of the smartphone cameras beyond personal and social photography. Consequently, applications (apps) based on smartphone cameras emerge, such as barcode readers, document digitizing tools, augmented reality, translation tools, and indoor positioning device. These apps benefit users and facilitate them in their daily life activities.

Modern mobile phones or smartphones have become a pervasive and affordable device for users at different levels of age around the world. Smartphones equipped with many useful sensors, including camera, barometer, accelerometer, and digital compass. The sensors on smartphones attracted researchers and developers to develop mobile applications (apps) and study the potential use of the sensors to support daily life activities. Unlike other types of sensor, the smartphone camera has been underutilized. Analysis of the literature suggested that smartphone camera mainly serves for personal and social photography. Practically, a smartphone camera can be used as an imaging device for reading a barcode. Although barcode has been used for identifying products and items, the use of a smartphone camera as a reading device has not been explored thoroughly. Further, scholarly resources describing the fundamental knowledge of smartphone camera barcode reading is not available in the literature which could be the reason contributed to slow research progress of the domain. Therefore, this study aims to review the current trends and future directions of smartphone camera for barcode reading. Specifically, the study reviews the literature on the types of applications that are currently available and run on the standard mobile platform for reading a barcode. It also analyzes the necessary components that made up barcode reading apps. Further, the review identifies technical and non-technical issues that are critical for the development of the apps. The contributions of this work are twofold, first, it provides the fundamental knowledge on the building blocks of camera barcode reading apps, and second, it explores the issues in the current camera barcode reading apps that could encourage exploration towards addressing the issues. Practically, the findings could spark new research ideas to address the current issues related to the use of smartphone camera for barcode reading in the near future.

Abstract: A multiplexed, ratiometric method is described that can confidently distinguish between cancerous and noncancerous epithelial prostate cells in vitro. The technique is based on bright surface-enhanced resonance Raman scattering (SERRS) biotags (SBTs) infused with unique Raman reporter molecules, and carrying cell-specific peptides. Two sets of SBTs were used. One targets the neuropilin-1 (NRP-1) receptors of cancer cells through the RPARPAR peptide. The other functions as a positive control (PC) and binds to both noncancerous and cancer cells through the HIV-derived TAT peptide. Point-by-point 2D Raman maps of the spatial distribution of the two tags were constructed with subcellular resolution from cells simultaneously incubated with the two sets of SBTs. Averaging the SERRS signal over a given cell yielded an NRP/PC ratio from which a robust quantitative measure of the overexpression of the NRP-1 by the cancer cell line was extracted. The use of a local, on-cell reference produces quantitative, statistically robust measures of overexpression independent of such sources of uncertainty as variations in the location of the focal plane, the local cell concentration, and turbidity.
