摘要
提出一种结合形状特征和光谱特征对多光谱遥感图像进行分割的方法。首先确定形状因子和光谱因子的表达式,然后应用区域生长算法在给定区域异质性阈值的约束条件下进行图像分割。实验结果表明此方法对中高分辨率多光谱遥感图像的分割效果较好,有一定的推广价值。
A multispectral remote sensing image segmentation method combined with shape feature and spectrum feature is proposed. First, the expressions of shape factor and spectrum factor are defined,and then,in the region-growing step,we take the threshold of region-heterogeneity as criteria to determine whether the growing process should be terminated in this direction.Experimental results show that this approach is effective to segment medium-high resolution multispectral remote sensing image and worthy to generalize.
