  • Image binarization based on grey membership parameter of pixels
    Patent number: 8744208
    Abstract: 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.
