傅里叶变换成像光谱数据压缩
Fourier Transform Imaging Spectral Data Compression
【摘要】 通过对傅里叶变换成像光谱仪数据的高低频反演光谱与光程差间的关系进行分析,提出一种光谱插值预测与量化编码压缩方法.仿真结果表明,在相对光谱二次误差<1%的情况下,压缩比优于5∶1.
【Abstract】 Large amount of data acquired by Fourier Transform Imaging Spectrometer(FTIS)needs to be compressed during transferring.Almost all methods show low efficiency in FTIS data compression.According to analyzing relationship between the high/low recovery spectrum and optical path difference,a Spectral Interpolating Prediction and Quantization Coding(SIP&QC)method is proposed.The 5∶1 compression rate is acquired with the Relative Spectral Quadratic Error(RQE)less than 1%.
