Abstract

A significant research problem being investigated for a very long time is Text detection and localization from natural scene images. It is a necessary technique for providing solutions to various applications such as intelligent transport systems, content-based retrieval systems, blind assistants and tour guide systems etc. Text found in scene images contains beneficial information for the needs and safety of people. Hence, it is essential to detect text and extract it for further application processing by computer vision systems. Text detection from scene images poses several challenges: varying illumination, low resolution, font size and style variations, complex backgrounds, presence of noise and other degradations. Various attempts are made to localize text from outdoor natural scene images, and this paper provides an exhaustive literature review of all existing methods and provides comparatives analysis. The way forward for future researchers is also reported.
