融合非局部空间灰度信息的三维Otsu法
Three-dimensional Otsu's method with non local spatial gray information
摘要
Abstract
In order to improve the robustness of the maximum between-cluster variance thresholding segmentation method (Otsu) to image noise, a three-dimensional Otsu's method with the non local spatial gray information is proposed. The gray information, the neighboring median gray information and the non local spatial gray information of the pixel are utilized to perform histogram statistics. A novel three-dimensional histogram is constructed. The maximum between-cluster variance is adopted as the threshold selection rule. Experimental results show that the proposed method is more robust than the traditional three-dimensional Otsu's method and can obtain more satisfying segmentation performance.关键词
