【Abstract】 The computational complexity of the traditional 2D entropic algorithm is bounded by O(L 4) .In this paper,a fast 2D entropic thresholding method whose computational complexity is only O(L 2) is proposed.Experimental results show that the processing time of each image is reduced from more than 2 h to less than 10 s.The required memory space is also reduced.更多还原
