Improved Degraded Document images Using Phase Based Binarization

Image binarization plays major role for document image binarization. Scanning and printing of documents can degrades their visibility that makes difficult to understand them. This paper has proposed a new technique which has ability to binarized documents in efficient manner. In the proposed method, a phase-based binarization model for document images is proposed, as well as a post processing method that can improve any binarization method and a ground truth generation tool. In the pre-processing and binarization steps the features are mainly phase derived while in the post-processing specialized adaptive Gaussian and median filters are considered..This technique also uses adaptive Gaussian filter to improve the accuracy rate further. Finally ground truth generation tool called Phase GT to simplify and speed up the ground truth generation process for
