Effect of digitization and globalization has narrowed down the gap of geographical boundaries.Text/language plays an important role in getting connected with people utilizing oral or written communication.Nowadays text data is easily available in the form of multimedia e.g.audio, videos.A technique is needed to understand and interpret the text present in the videos/images which are rich in contents compared to audio data.Text detection and recognition are two main steps of such text-based applications.Text detection from natural scene images is tedious compared to text detection from document images.Various methods are available for text detection from natural scene images.Text detection methods are generally script specific.The main purpose of this paper is to highlight available text detection methods with pros and cons, challenges in the text detection process, evaluation parameters as well as recent achievements.The paper will act as a roadmap for upcoming researchers to select an appropriate text detection method.
