A Review of Image Binarization Techniques for Ancient Degraded Documents

Punam A. Mahajan | Swati A. Patil ^[2]

Abstract: Image BinarizationTechnique depends on the segmentation technique which is major technique for separation of pixel values such as black as foreground and white as background. Segmentation of the degraded document images can be done by using image binarization techniques in order to acquire a clear image which will be visible means which is easy to understand them. Thresholding technique and Contrast image construction are the important techniques for degraded document image binarization. For this document binarization technique, many binarization techniques has been proposed

Keywords: Recursive Thresholding, Gabor Filter, Contrast Image Construction, Contour Based Image Segmentation
