ABSTRACT
Visually impaired individuals face significant challenges in distinguishing between different denominations of Indian currency notes, which hinders their ability to perform routine tasks such as shopping and financial management. Traditional methods of currency recognition, such as tactile features or optical scanners, are often burdensome and inconvenient. This groundbreaking system utilizes a deep learning model developed from a vast dataset of Indian rupee notes captured in diverse environments, including various orientations, stages of wear-and-tear, and lighting conditions, ensuring robust training. By leveraging Convolutional Neural Networks (CNNs), the system ensures a high degree of accuracy in identifying notes and generates distinct audio cues corresponding to each denomination, simplifying the differentiation process for visually impaired individuals. The use of neural networks enables the system to continuously refine its recognition capabilities, adapting and improving its identification methods with additional data, including updated note variations or unexpected scenarios. Upon widespread availability, this technology has the potential to revolutionize how blind individuals in India manage their finances, providing them with increased autonomy and confidence in everyday transactions. The proposed system offers several advantages over traditional currency recognition methods: it is non-invasive, requiring no physical contact with the currency notes, thus enhancing convenience; its portability enables implementation on mobile devices, facilitating access for users on the go; and it prioritizes user-friendliness by providing real-time audio feedback, further simplifying the currency identification process for visually impaired individuals. Overall, this innovative solution represents a significant stride towards empowering the visually impaired community in India, offering newfound freedom and self-assurance in managing their monetary affairs.
