摘要
基于GEOEYE-1多光谱影像、以归一化差分植被指数(NDVI)为研究对象继续就分形方法在高空间分辨率基础图影像中的适用性进行研究,并就分形模型构建最合理尺度层级的确定进行细致探讨.实验表明,基于分形理论的NDVI连续空间尺度转换模型构建方法适用于高空间分辨率遥感影像; 在给定的条件下,NDVI尺度转换分形模型构建时最合理尺度层级存在且可计算.研究使得分形方法所适用的反演量类型及基础图空间分辨率范围皆有大的扩展.
Abstract
The continuous spatial scaling model (CSSM) of NDVI based on fractal theory was proposed and implemented. Based on GEOEYE-1 image and taking NDVI as experimental object, the paper studied the availability of fractal methodology for high-resolution image, and discussed the selection of the best reasonable scale-level for establishing NDVI's CSSM. It was concluded that the fractal methodology is suitable for high-resolution RS image. In some definite conditions, the best reasonable scale-level for establishing NDVI's CSSM exists and can be computed. For the fractal methodology, the results in the paper extended its available range of retrievals and image's resolutions.
