Thresholding is a fundamental operation in image processing. Based on the pairwise nearest neighbor technique and the variance criterion, this theme presents two fast adaptive thresholding algorithms. The proposed ΓΏrst algorithm takes O((m -k)m ) time where k denotes the number of thresholds speciΓΏe
