【摘要】

：

FY-3B中分辨率光谱成像仪(MERSI)不能实现可见光近红外波段的星上绝对定标。为了提高MERSI高信噪比窄波段通道的辐射定标精度,针对国际通用的6个北非沙漠目标,利用高质量的SeaWiFS数据构建天顶双向反射分布函数(BRDF)模型,借助MODTRAN辐射传输模型和ERA-Interim再分析资料吸收气体数据构建光谱匹配因子,对FY-3B MERSI 5年的在轨运行数据进行交叉定标研究。所构建

基于卷积神经网络的端到端多光谱图像压缩方法

针对多光谱图像的空谱相关特性,提出一种基于卷积神经网络的端到端多光谱图像压缩方法。编码端,将多光谱数据整体输入到多光谱图像压缩网络中,采用卷积提取多光谱图像的主要光谱特征与空间特征,使用下采样减小特征数据的尺寸,并通过率失真优化控制光谱特征与空间特征数据的熵,使空谱特征数据分布更加紧凑,将量化后的中间特征数据进行无损熵编码得到压缩码流。解码端,码流经过熵解码、逆量化、上采样、反卷积的逆变换过程重构
