Abstract:
Deals with the extraction of binary character/graphics images from grayscale document images with background pictures, shadows, highlight, smear and smudge. The authors review four published extraction techniques, and present a new technique. They then propose speed, memory requirement, stroke width restriction, parameter number, parameter setting and human subjective evaluation of result images as six aspects for evaluating and analysing extraction techniques. The result of systematically evaluating and analyzing both new and published techniques with experiments on images of typical check images and poor-quality text documents with respect to these six aspects is reported
