Script Identification for Document Image Retrieval: A Survey

In recent years there are many multimedia documents captured and stored with the advances in computer technology and hence the demand for recognizing and retrieval of such documents has increased tremendously .In such environment the large volume of data and variety of scripts make manual identification unworkable. In such cases the ability to automatically determine the script ,and further the language of a document would reduce the time and cost of document handling. So the development of script identification from multilingual document image systems and then retrieving document image by matching with a query image (input image) has become an important task. In this paper, we present a survey of methods developed to identify the script in document images automatically without manual intervention and then to access the document images by matching with the input query image, General Terms: Script identification, Document image retrieval, Language identification Techniques, Phase based image matching, Feature extraction.
