Fuzzy Logic Based Perceptual Image Hashing Algorithm in Malaysian Banknotes Detection System for the Visually Impaired

Visually impaired persons have difficulty in business that dealing with banknote. This paper proposed a Malaysian banknotes detection system using image processing technology and fuzzy logic algorithm for the visually impaired. The Malaysian banknote reader will first capture the inserted banknote image, sending it to the cloud server for image processing via Wi-Fi medium. The cloud server is established to receive the banknote image sending from the banknote reader, processing them using perceptual hashing based image searching and fuzzy logic algorithm, then return the detected banknote’s value results back to the banknote reader. The banknote reader will display the results in terms of voice message played on the mini speaker attached on it, to allow visually impaired persons knowing the banknote’s value. This hardware mechanism reduces the size and costs for the banknote reader carried by the visually impaired persons. Experimental results showed that this Malaysian banknotes detection system reached an accuracy beyond 95% by running test on 600 different worn, torn and new Malaysian banknotes. After the banknote image being taken by the banknote reader’s camera, the system able to detect the banknote value in about 480 mili-seconds to 560 mili-seconds for a single sided banknote recognition. The banknotes detection speed was also comparable with human observers reading banknotes, with the response of 1.0908 second per banknote slight difference reading time. The IoT and image processing concepts were successfully blended and it provides an alternative to aid the visually impaired person their daily business transaction activities in a better way

The Necessity of Close Contact Tracing in Combating COVID-19 Infection – A Systemic Study

Many contact tracing solutions developed by countries around the globe in containing the Covid-19 pandemic are in the area of location-based tracing, which does not enable them to identify close contacts accurately. As location-based tracing implementations continuous on, the results have not been as effective as intended. Thus, in providing some closure, this study will dissect the need for close contact tracing solutions for the pandemic by providing a comprehensive contact tracing characteristic framework (CCTCF) for Covid-19, which will help authorities toward better pandemic management. In this study, CCTCF for Covid-19 was constructed by applying several methods. Using Problem, Intervention, Comparison, Outcome (PICO) as the framework, methods conducted were: (1) Case study to analyze the contact tracing systems in 30 countries; (2) Systematic literature review (n=2056) regarding solutions’ elements, (3) Thematic analysis for characteristics framework development. A total of 25 items were obtained for CCTCF, along with valuable insights that necessitate close contact tracing for the pandemic. Results from CCTCF have also shown that the best contact tracing solution for Covid-19 is bi-directional human-to-human close contact tracing, which uses a retrospective approach and is able to identify the source as well as groups of infection using a personal area network (PAN). Doi: 10.28991/esj-2022-SPER-019 Full Text: PD

Fuzzy Logic Weighted Averaging Algorithm for Malaysian Banknotes Reader Featuring Counterfeit Detection

This paper proposed a novel fuzzy logic weighted averaging (FLWA) algorithm in image processing techniques to detect counterfeit Malaysian banknotes. Image acquisition techniques on banknote position detection and re-adjustment, image pre-processing techniques, feature extraction methods on Malaysian banknotes’ watermarks are also covered in the paper. The FLWA Algorithm has the advantage of a much simpler model since it is a human guidance learning algorithm that does not require enrolment process to get the specific weights for each security feature. Each security feature is treated with equal weight. The experimental results also shown that FLWA model also outperform the MobileNet model and VGG16 model in Malaysian banknotes’ counterfeit detection. It has a distinct advantage over earlier or current banknote counterfeit detection techniques in that it adopted the known watermarks features, with known machine learning techniques to identify real Malaysian banknotes and detect those counterfeit Malaysian banknotes

In this ricediagnosis are taken as the cases of Case Base. Moreover, cosinesimilarity algorithm is used for measuring the similar cases

Storage Locker Featuring Voice Activation for Visually Impaired

Abstract: People who are visually impaired find it is challenging to temporarily store their precious or personal belongings to keep them safe. To improve their quality of life, visually impaired individuals need a storage locker equipped with assistive technology where they may store their valuables or personal items while they are at home or on the go. The voice-activated storage locker for the visually impaired individuals that is proposed in this study involve a voice recognition module, voice playback, a micro servo motor, and a braille keypad. With these integrated features, it will be easier for visually impaired individuals to operate the storage locker, which will boost its efficacy. A rotating mechanism would be activated by an electronic system built within the lock employing a servo motor. To make them easier for those with visual impairments to operate, standard storage locker types have been upgraded to include digital voice control. The results of a test conducted on 20 people with visual impairments showed that accurate passwords spoken by the user could lock and open the storage locker with an accuracy of up to 95%

An Innovative Approach to Developing a 3D Virtual Map Creator using an Ultrasonic Sensor Array

Human shifted their focus towards robots once realizing that the robots may serve for the human development with the increased complexity of the living structures and the rapid revolutions in field such as manufacturing and civil structures. This paper investigates the development of a mobile robot that utilizes ultrasonic sensors to obtain distance readings and utilize it to draw 3D map of its surrounding. The robot is designed to perform within narrow spaced as well as rough terrain environment such as underground piping structure or underground wiring networks. The chosen wheeled platform is capable of maneuvering through the rough surfaces, guided by a specially designed obstacle navigation strategy using ultrasonic sensors. The mounting of the 3D mapping sensors presented in this paper is a new and innovative approach that resolves many of the problems encountered through previous proposed designs of 3D ultrasonic mappers. The 3D mapping sensors obtain data that creates a 2D map along with the position localization data to create a 3D form.

Development and Testing of an Active Automated Car Spoiler

Automotive aerodynamics have long been a focus of research in order to improve vehicle performance and fuel efficiency. One method of improving aerodynamics is through the use of spoilers, which create downforce on the rear of the vehicle and help to stabilize it at high speeds. However, traditional spoilers are passive and cannot adjust their angle of attack based on changing conditions. The purpose of this study was to design and test an active automated car spoiler with an adjustable angle of attack in order to optimize its performance at different speeds. The spoiler was designed to be 140-180 cm wide and equipped with force-sensitive resistor (FSR) sensors to provide feedback on its performance. The angle of attack was adjusted using this feedback in order to maintain optimal downforce at different speeds. The active automated car spoiler was able to significantly improve the aerodynamic performance of the vehicle, resulting in increased stability and fuel efficiency. Further testing and optimization of the design is necessary in order to fully realize the potential of the active automated car spoiler. This study presents a novel approach to improving automotive aerodynamics through the use of an active automated car spoiler with adjustable angle of attack
