Abstract: Image segmentation is the key step to do image processing and image analysis. Thresholding segmentation method is widely used for its simpleness and the clustering algorithm also plays an important role in the image segmentation field. Some millimeter wave images are processed by certain classic thresholding segmentation algorithms and several clustering ones. As evaluation standard, misclassification error, uniformity measure, gray-level contrast are implemented to compare segmentation performance of each algorithm.

Key words: clustering algorithm, image segmentation, thresholding segmentation, evaluation

摘要: 图像分割是图像处理到分析的关键步骤,阈值分割方法因其计算简单而被广泛应用,聚类算法也因其准确性成为图像分割领域中一类极其重要的算法。选取几种经典阈值分割算法和几种聚类算法对几幅毫米波图像进行分割实验,并引入错分类误差、均匀测度、区域间灰度对比度作为算法测评标准,比较了各种算法对毫米波图像的分割性能。
