A Fast Two-dimensional Entropic Thresholding Algorithm

摘要：

Two-dimensional thresholding method behaves well in segmenting images of low signal-to-noise ratio,but it s time consuming.In this paper,a fast algorithm is proposed based on recursive formula and search strategy.Firstly,this paper represents the concept of optimal 2-D entropy function. Then proposes an undistorted fast recursion method and a distorted optimal search strategy,so the proposed method can decrease computational time largely when it provides good quality segmentation.Finally we analysis and validate the algorithm by theory and experiment.
