ASYSST: A framework for synopsis synthesis empowering visually impaired

In an indoor scenario, the visually impaired do not have the information about the surroundings and finds it difficult to navigate from room to room. The sensor-based solutions are expensive and may not always be comfortable for the end users. In this paper, we focus on the problem of synthesis of textual description from a given floor plan image to assist the visually impaired. The textual description, in addition to a text reading software, can aid the visually impaired person while moving inside a building. In this work, for the first time, we propose an end to end framework (ASYSST) for textual description synthesis from digitized building floor plans. We have introduced a novel Bag of Decor (BoD) feature to learn 5 classes of a room from 1355 samples under a supervised learning paradigm. These learned labels are fed into a description synthesis framework to yield a holistic description of a floor plan image. Experimental analysis of real publicly available floor plan data-set proves the superiority of our framework.
