Decompose algorithm for thresholding degraded historical document images

  title={Decompose algorithm for thresholding degraded historical document images},
  author={Yan Chen and Graham Leedham},
Numerous techniques have previously been proposed for single-stage thresholding of document images to separate the written or printed information from the background. Although these global or local thresholding techniques have proven effective on particular subclasses of documents, none is able to produce consistently good results on the wide range of document image qualities that exist in general or the image qualities encountered in degraded historical documents. A new thresholding structure… CONTINUE READING
