Two related MRF models, an edge-preserving smoothing model followed by a modified standard regularisation, are presented for the adaptive binarisation of nonuniform images in the presence of noise. In particular, a computational model is developed for a modified standard regularisation method which calculates the adaptive threshold surface for noisy images. Since the modified standard regularisation depends only on the image data, and not its edge segments, it gives much better performance and can be applied to more classes of image than those methods that solely rely on edge segments. Experimental results demonstrate that the proposed method has the best performance over three other commonly used adaptive segmentation methods and is faster than previous interpolation-based thresholding techniques.
