Portable offline indoor object recognition system for the visually impaired

Research output: Contribution to journalArticle


This paper presents an indoor assistive system that addresses the challenges faced by Visually Impaired (VI) individuals. The proposed system helps the VI individuals to move freely indoor and make them independent of any external assistance. The proposed system consists of a compact unit with a camera and accompanying sensors providing an efficient, convenient and cost-effective solution. The performance comparison with two existing systems shows that the proposed system provides a very close performance to the benchmarks with advantages of portability and no requirement for cloud services.
