WebIn this paper, we propose an anisotropic diffusion model involving fuzzy-based source for binarizing degraded document images, in which the diffusion term is response for edge-preserving smoothing and the source term is used to group intensity values of foreground and background pixels into two dominant modes separated by zero. WebThe method is the implementation of the Adaptive Thresholding Methods for Documents Image Binarization Research Paper (link given at the bottom). The image is first converted to grayscale to apply a thresholding technique, then Sauvola method is used to compute the threshold using mean and standard deviation of neighbouring window pixels.
