    • Briefly, in accordance with one aspect, a method of binarizing an image is provided. The method includes partitioning the image into a plurality of image segments, each image segment having a plurality of image pixels and partitioning each of the image segments into subsegments, each image subsegment having a plurality of image pixels. The method also includes estimating a grey membership parameter for each image pixel for each of the plurality of image segments and subsegments, combining the grey membership parameter for each of the plurality of image pixels from each of the plurality of image segments and subsegments to estimate a net grey membership parameter for each image pixel and assigning black or white color to each of the plurality of image pixels based on the estimated net grey membership parameter of the respective pixel.
    • 简而言之,根据一个方面,提供了一种二值化图像的方法。 该方法包括将图像分割成多个图像片段,每个图像片段具有多个图像像素,并且将每个图像片段划分成子片段,每个图像子片段具有多个图像像素。 该方法还包括针对多个图像段和子段中的每一个为每个图像像素估计灰色隶属度参数,从多个图像段和子段中的每一个组合用于多个图像像素中的每一个的灰色隶属参数,以估计一个 基于每个像素的净灰度隶属参数,并且基于相应像素的估计的净灰度隶属度参数,将多个图像像素中的每一个分配黑色或白色。
