STIF）作为一种可行性高、成本低的获取高时空分辨率遥感影像的方法，对促进现有对地观测数据的深度应用是很重要的。</p><p style="white-space: normal;margin: 0px;padding: 0px;box-sizing: border-box;"><br style="box-sizing: border-box;"

style="white-space: normal;margin: 0px;padding: 0px;box-sizing:

border-box;">讨论部分：</strong>作者通过综合考虑地表的物候变化和复杂的土地覆盖变化，提出了RASTFM来解决各种景观中的复杂地表变化，该算法仅需一对先验的低-高分辨率影像就能生成可靠的高分辨率时间序列影像。作者将RASTFM与STARFM，FSDAF和单对影像学习方法进行了比较，证明了RASTFM在对复杂地表变化的时空融合中具有优越性。<strong style="box-sizing: border-box;">该算法的优点主要包括：</strong></p><p style="white-space: normal;margin: 0px;padding: 0px;box-sizing: border-box;">（1）是具有非形状和形状变化模块的像元级和特征级STIF方法的组合；</p><p style="white-space: normal;margin: 0px;padding: 0px;box-sizing: border-box;">（2）所提出的NL-LR理论将影像的非局部相似性和局部结构规律集成到一个模型中，实现了更精确和稳健的估计；</p><p style="white-space: normal;margin: 0px;padding: 0px;box-sizing: border-box;">（3）基于NL-LR的非形状变化预测模块继承和推广了STARFM预测框架的优势，同时克服了它的局限性（相似相邻块的选择与权重计算），从而获得了更可靠的相似性邻近图像块及对应权重；</p><p style="white-space: normal;margin: 0px;padding: 0px;box-sizing: border-box;">（4）在特征级的形状变化预测模块中使用了基于NL-LR的两层影像超分辨率重建方法，强化了光谱和几何结构的相似性，保证了权重的精确性和鲁棒性；</p><p style="white-space: normal;margin: 0px;padding: 0px;box-sizing: border-box;">（5）基于回归的高通调制消除掉了由于加权平均所导致的影像平滑效果。</p><p style="white-space: normal;margin: 0px;padding: 0px;box-sizing: border-box;"><br style="box-sizing: border-box;"

0px;box-sizing: border-box;">作者提出了一个鲁棒的STIF模型（RASTFM），用于在仅有一对可用的低-高分辨率影像的情景下融合多时空分辨率的卫星影像。将NL-LR理论、图像超分辨率重建方法、以及经典的STIF算法（STARFM）结合起来，从而形成了一个综合的时空融合理论框架，并基于这些理论来处理不同景观中复杂的地表变化。此外除了本文所选取的Landsat-MODIS之外，其他具有相似波段设置和轨道参数的传感器所获得的卫星影像也适用。如Sentinel-2A/B MSI和Landsat-8 OLI。该模型结合当前的STIF理论和相关的图像超分辨率重建理论推进了时空融合算法的研究，同时也为自然或人为因素所引起的复杂地表变化的连续监测提供了更好的数据源。然而，虽然该方法已经被证实了有较好的稳健性和预测性能，但在微小的地表变化预测、不确定性分析方面仍有进一步的改进空间。尽管随着对地观测系统的发展，有越来越多可用的中、高分辨率卫星影像，但是云污染依旧是对地观测数据来源的大问题，通过STIF 能够在一定程度上弥补云污染对高分辨率影像的可用性所带来的影响。同时各类用户对高时空分辨率卫星影像的需求也在日益增加，比如高空间分辨率的地表温度日循环监测、城市地区的空气污染实时监测、多尺度的地表日蒸散发监测。所以，在此背景之下STIF依旧有其现实意义，但是STIF并不能替代实际的卫星传感器。</p><p style="white-space: normal;margin: 0px;padding: 0px;box-sizing: border-box;"> </p><p style="white-space: normal;margin: 0px;padding: 0px;box-sizing: border-box;">小编惊叹于这篇文章所提出的STIF模型理论框架的严密，对经典的STIF理论和图像处理领域兴起的图像超分辨率重建框架的深刻理解以及完美地结合，同时应用二者在STIF过程中对复杂的地表变化（尤其是土地覆盖的非形状和形状变化）进行预测，这也是该篇文章的最主要创新点。同时用来比较的其他STIF算法涵盖了目前STIF研究领域的前沿算法，可以说在遥感影像时空融合领域是一篇重要的文章。而文章目前的缺憾，仍旧集中在对Landsat和MODIS影像的融合，暂时没有涉及到其他的卫星影像；另外关于STIF的数据支撑对地观测的应用也谈得较少。</p><p
