threshold selection is crucial.For traditional Otsus algorithm exists threshold deviation cause poor image segmentation problem
a kind of fuzzy judgment Otsu image segmentation algorithm has been proposed. Though the process of Otsus threshold fuzzy judgment
by the gravity method for searching the threshold to get a result of segmenting image better. Experimental results show that the proposed algorithm can get better result compared with one-dimensional Otsus algorithm and two-dimensional Otsus algorithm.
