高分辨率遥感图像分割的最优尺度选择

摘要

The problem of best segmentation scale is a key point in multi-scale segmentation of high-resolution image segmentation. The confirmation of the best segmentation has a direct effect on the extraction and analysis of the information gathered from the image. This paper puts forward a best segmentation scale model in overall situation on the basis of model calculation. This model can calculate the best segmentation scale on the consideration of multi-band information, therefore, avoiding the potential subjectivity of human visual.%面向对象的最优尺度选择是高分辨率遥感图像多尺度分割技术中的关键问题。最优分割尺度的确定直接影响到后续的图像信息提取与分析。在模型计算法的基础上，改进并实现了一种全局最优尺度计算模型。该最优尺度计算模型可以根据多波段信息自动选择最优尺度，从而避免了人目视的主观性。
