摘要
绿地与人们的生产、生活密切相关,绿地是城市的净化器,发挥着保持水土、涵养水源、调节自然界生态平衡等重要作用。本文主要讨论了面向对象的分类技术,研究了多尺度影像分割和基于高分辨率影像的信息提取方法,在实验的基础上与传统的基于像元统计方法的信息提取结果进行了比较。结果表明,面向对象的信息提取方法在高分辨率遥感影像绿地信息提取中具有明显优势,可大大提高分类效率和精度。
Green fields play an important role in people＇s life. They can purify the air, conserve water, and regulate the ecological balance. The paper mainly studied the multi - resolution segmentation technology and information extraction by using classification methods of object - oriented neighborhood and fuzzy comparison analysis of traditional methods on the basis of pixels （ maximum likeli- hood method ） and object- oriented method of extraction results. The results show that ,object- oriented method in green space infor- mation extraction from high resolution remote sensing image has a significant advantage.
