The minimax probabilistic machine is a classifier based on minimizing the misclassification probability. The problem of 1-dimensional minimax probability machine is firstly discussed. Then a theory on minimax probabilistic image segmentation is presented. A method for developing criterion function for image thresholding is proposed. Meanwhile, the minimax probabilistic image thresholding algorithm is also proposed and it ensures the maximal lower bound for correctly classifying pixels. Experimental results show the effectiveness of the proposed algorithm.
