| Abstract: | Base on the characteristics of the trapezius narrowband verdict scope of 2D Otsu adaptive threshold fast algorithm. Through the establishment of distribution data of the information association between narrowband trapezius intercept and image pixel two-dimensional probability density, this paper proposes a dynamic trapezius intercept narrowband adaptive selection method without increasing complexity. The experimental result has demonstrated that the improved fast algorithm of two-dimensional Otsu adaptive threshold was more adapted to the actual condition of image segmentation, and has achieved good effect. |
