Currency Identification Device for Visually Impaired People Based on YOLO-v5 ABHIRAMI B ¹, GOPIKA I¹, HASAN A R¹, IJAZ MUHAMED N J¹, AISWARYA S S² ¹UG Scholar, Department of Computer Science and Engineering ²Asst.Prof, Department of Computer Science and Engineering UKF College of engineering and technology Kollam, Kerala, India ---------------------------------------------------------------------------***-------------------------------------------------------------------------Abstract: A normal human being can easily identify and recognize any banknote, but it is extremely difficult for a visually impaired or blind individual to do so. Currency plays a significant role in our daily lives and real-time detection and analysis are required for any commercial transaction. Detecting banknotes seems to have become a necessity for a person especially for those who are blind or have visual impairments. There is a large number of visually impaired persons in India. The currency notes are almost same in thickness and some are also in similar size, which make difficult to visually impaired person to identify currency notes. The YOLO-v5 CNN model-based banknote detection and recognition device is proposed for this purpose, and it is fast and accurate. Photos of various denominations and circumstances were initially collected, and then these images were enhanced with various geometric and visual alterations to make the system more resilient. These augmented photos are then manually labelled, and training and validation image sets are created from them. Later, the trained model's performance was assessed on a real-time scene as well as a test dataset. The suggested YOLO-v5 model-based technique exhibits detection and recognition accuracy of 96.5 percent according to the test results. The entire system is self-contained and operates in real time.

INTRODUCTION Over 2.2 billion people worldwide suffer from visual impairment, including 1 billion people with severe or acute distance vision impairment or blindness, the majority of whom are over 50 years old [1]. Glaucoma, cataracts, untreated presbyopia, and refractive error are the most common causes of debilitation. According to the World Health Organization, the number of persons affected by visual impairment will more than double by 2020. Assistive devices, such as walking dogs or white canes, are commonly used by visually impaired people. The white cane is most usually chosen for reasons such as low cost, portability, and widespread acceptance within the blind population. However, when faced with a range of obstacles and conditions in their daily lives, these assistance devices have their own limitations. People frequently regard such individuals as a burden and leave them to fend for themselves. As a result, the visually impaired individual requires the assistance gadget on a regular basis, which can assist in their day-to-day responsibilities and rehabilitation. People in their eighties and nineties have a higher risk of vision loss for those with visual impairments, the assistive system plays an important role in social situations. It feels difficult without this assistive equipment they're reliant on others. In addition, the cost of rehabilitation is out of reach for low-income people. Currently, India has around 12 million blind people which makes India home to one-third of the world's blind population [2]. So, a real-time Indian currency detection device will be very much beneficial for visually impaired persons in India. Several frameworks and strategies for healthcare services have been created in the last decade. The goal of these improvements is to lower the cost of medical diagnosis while also assisting the health sector with technology that allows people to self-manage their lives more readily than ever before without the need for direct supervision from an expert. People with impairments, on the other hand, were not the primary beneficiaries of these achievements. However, there is a pressing need for technology that may help and assist people in their daily lives, improve their living in a simple way, and lead to independence. Visual Impairment has to be the most serious of these disabilities. Currencies are significant as a medium of buying and selling goods. Each country has its own currency, which comes in a variety of colors, sizes, shapes, and patterns. Visually challenged people find it difficult to detect and count different denominations of currency. Due to continual use, tactile marks on the banknote's surface evaporate or fade away, making it
