| 摘 要： | 研究了灰度图象的二维ｏｔｓｕ自动阀值分割法．根据灰度图象的象索点灰度，邻域均值二维直方图的分布特点，给出了一个新的分割阀值判决函数．理论分析与实验结果表明：该阀值判决函数比仅使用一个二维矢量阀值具有更强的抗噪声能力，分割性能更好．

| Abstract: | Two dimensional otsu thresholding for grey image segmentation was discussed. A new thresholding output function was discussed. A new thresholding output function was given based on the distribution features of 2 D histogram (grey level/local average level). The Theoritical analysis and comparative experimental results show that this new function performs are much better when the image are corrupted by noise. |
