Abstract: A method based on signal matching to binarize low signal-noise rate image was proposed. The information from image interference of both complex background and seal noise could be extracted. Making full use of the prior knowledge, the image projection function under ideal condition would be obtained. By using this signal to match the projection functions binarized by different thresholds, the optimum threshold was in fact the threshold which projection function match best. This method is more self-adaptive and robust than other traditional methods. Through experiments, when compared with other algorithms, satisfactory results were got.

Key words: projection signal, signal matching, printed check date area, binarization
