简介:Hyperspectral遥感图象地面分类面对高数据维数的问题和训练数据标记的缺乏,导致未得到满足的地面分类效率。特征抽取为保存歧视的信息并且减少数据维数在地面分类前被要求。Ahyperspectral遥感图象特征抽取方法,即,分离余弦变换(DCT)光谱回归判别式分析(SRDA)subspace方法,被介绍解决上述问题。建议DCTSRDAsubspace方法第一在原版拿DCT光谱空间并且得到每个象素的DCT系数光谱曲线;第二在DCT系数空间执行SRDA并且获得DCTSRDAsubspace。最小的距离分类器在产生DCTSRDAsubspace被设计评估特征抽取表演。试验因为二幅真实在空中的可见/红外线的成像分光计(AVIRIS)hyperspectral图象显示出那,与作比较光谱LDAsubspace方法,建议DCTSRDAsubspace方法能改进地面分类效率。

简介:无人的天线车辆(UAV)遥远的成像被坏天气影响,并且获得的图象有低对比的劣势,复杂质地并且变模糊。在这份报纸,我们基于多重散布建议一个盲目deconvolution模型空气点传播功能(APSF)评价到恢复遥感图象。根据Narasimhan分析理论,一个新多重散布恢复模型基于改进二色的模型被建立。然后使用L0标准到估计APSF污迹核的坡度和黑暗隧道的稀少的priors,快Fourier变换被用来由过滤的维纳恢复原来的清楚的图象。由与另外的最先进的方法作比较,建议方法能正确地估计污迹核,有效地移开大气的降级现象,保存图象详细信息并且增加优秀评估索引。
