Recent trends in computer vision-driven scene understanding for VI/blind users: a systematic mapping

Abstract During the past years, development of assistive technologies for visually impaired (VI)/blind people has helped address various challenges in their lives by providing services such as obstacle detection, indoor/outdoor navigation, scene description, text reading, facial recognition and so on. This systematic mapping review is mainly focused on understanding aspect (e.g., object detection) solutions. It provides guidance researchers this field to understand advances during last four a half years. because deep learning techniques together with computer vision have become more powerful accurate than ever tasks like detection. These advancements can bring radical change high-quality VI/blind users. Additionally, an overview current comparison between different solutions provided indicate pros cons existing approaches.
