简介:高分辨率图象熔化是图象处理的域里的一个重要焦点。一个新图象熔化模型基于实验模式分解(EMD)的典型水平被介绍。多光谱的图象的紧张色彩浸透(代表耶稣之符号)变换首先给紧张图象。此后,以ID的排列扩展,EMD建模的2DEMD被用来从高分辨率的乐队图象和紧张图象分解详细规模图象和粗糙的规模图象。最后,一幅熔化紧张图象被重建在熔化图象与高分辨率的图象的高频率和紧张图象和代表耶稣之符号反的变换结果的低频率获得。在介绍EMD原则以后,2DEMD的一个多尺度的分解和重建算法被定义,一个熔化技术计划基于EMD是先进的。全色的乐队和多光谱的乐队3,2,1Quickbird被用来估计熔化算法的质量。在在特定的排(列)上根据EMD分析为兼并选择适当内在的模式函数(IMF)以后,象素灰色珍视系列,熔化计划给一幅熔化图象,它与通常使用的熔化算法相比(小浪,代表耶稣之符号,Brovey)。图象熔化的目的包括提高图象的可见性并且改进空间分辨率并且光谱原来的图象的信息。为了估计一幅图象的质量,在熔化,信息熵和标准差被使用估计熔化图象和相关系数的空间细节以后,为测量在原来的图象和熔化图象之间的失真以偏导索引和变弯的度光谱信息。为建议熔化算法,当EMD算法被用来执行熔化经验时,更好的结果被获得。
