A SURVEY ON BINARIZATION TECHNIQUE

Computer Engineering

Now-a-days, there are many activities which are depending on internet and there is huge need to shift all the activities which are performed by user towards the digitization of world. There are so many thesis and novels are exist which had been written many years ago and available in hard copies .But these documents are being degraded due to some natural or manual causes. Many of the document images are not in readable format. So, we need to separate out text from the degraded images. For this purpose, we will develop the system that can capable of separating the text from degraded images. In this proposed work, use of algorithms for separating foreground and background of image which includes image contrast inversion, edge estimation, image binarization and post processing of binary images is proposed. So, proposed system can able to separate out foreground text from background degradation after applying these algorithmic techniques. Therefore degraded documents will be enhanced in picture quality.
