Object Detection Methodologies for Blind People

Abstract

Vision is the most important sense. Image plays vital role in the human perception of the surrounding environment. However there are visually impaired people, industry has created a variety of computer vision products and services by developing new electronic technologies for the blind in order to overcome the difficulties. Digital image processing is the field which processes the digital image by using digital computer. An increasing interest in developing technologies attempts to help visually impaired people in their daily lives. It is shown that the object identification is the difficult task for visually impaired people . Although there are many applications that can be used for this task, there are still limitations that require more improving. For this reason, this paper provides the survey and an analysis of various evaluations for the technologies that used in the object identification task. For the visually impaired the idea of sensory substitution can be used.
