This letter describes a new thresholding method for recognizing pattern regions in noisy gray-scale images. Many previously developed thresholding techniques occasionally lead to unreasonable results for noisy images with small pattern occupancies. In the proposed method, the threshold is evaluated on the basis of the difference function of a pair of local histograms for two windows set in the image. The zero-cross point of the function is independent of both the noise spectrum and the pattern ratio, and it coincides with the true threshold. This method is a powerful tool for thresholding noisy gray-scale images that have unknown pattern ratios.
