Abstract: The automatic binarization of grey level images or the automatic determination of optimum threshold value that separates objects from their background is still a difficult and challenging problem in many applications in the area of digital image processing. A new algorithm is proposed for the optimum automatic thresholding of digital images. The algorithm is based on determining the best threshold value that maximizes a correlation function between the binary and original grey level images. Experimental results to compare the proposed algorithm to various thresholding techniques are also presented. 1.
