| Abstract: | Based on the characteristics of the trapezius narrowband verdict scope of 2D Otsu adaptive thresholdfast algorithm, and the same characteristic of obliqueline traversing anarrow bandregion, we proposed the establishment of algorithm auxiliary shaft which improved and simplified the realization of original fast algorithm. Compared to the original algorithm of dimension reduction, this algorithm simplify the implementation process and algorithm complexity. Results show that the improved fast algorithm of 2D Otsu adaptive threshold was more adapted to the actual condition of image segmentation, which has achieved good effect of image segmentation in experiment. |
