本文将5种图像分割算法应用在高分辨率遥感图像分割上,并利用图像分割评价指标,对5种分割算法进行了对比分析,评价了各种方法的优缺点,讨论了它们在高分辨率遥感图像分割中的适用性,明确了不同分割方法的适用条件。实验结果表明,改进的分水岭分割法与JSEG分割法在高分辨率遥感图像分割中的适用性比较强,对大小斑块分割结果都比较好,而其他3种方法不能兼顾不同等级的斑块。
In this paper, five kinds of image segmentation algorithms are applied to the high resolution remote sensing image segmentation. By using the image segmentation evaluation index, the five kinds of segmentation algorithms are compared and analyzed, the advantages and disadvantages of each method are evaluated, The applicability of remote sensing image segmentation, clear the different conditions of segmentation methods. The experimental results show that the improved watershed segmentation method and JSEG segmentation method are more suitable for high resolution remote sensing image segmentation, and the segmentation results are better for the large and small patches, while the other three methods can not take into account the different levels of patches.
