spectral absorption meaning in English

光谱吸收
频谱吸收

Based on the first two chapters , this paper researches feature extraction both from wavelet transform and spectral absorption features
在前面的基础上,论文分别从基于小波变换以及基于光谱吸收特征两个方面来研究特征提取方法。
The purpose of measuring spectral absorption spectral experiments is determined . the makeup of experiment instruments is introduced and the configuration of testing system is performed
确定了吸收光谱分析实验的目的，介绍了实验仪器设备的组成，对实验系统进行了配置。
Absorption - band parameters such as the position , depth , width , and asymmetry of the feature have been used to quantitatively estimate composition of samples from hyperspectral data . so spectral absorptions are very important feature bands in use of hyperspectral classification and targets identify , this paper extracts absorption features of actual hyperspectral image by continuum removed method which is very useful . then tested both of them by
吸收峰波段参数例如波长位置、深度、宽度、斜率、对称度、面积等常常被用来定量的估计高光谱样本的组成,因此光谱的吸收峰是高光谱识别分类应用中很重要的特征波段,论文通过包络线去除这种很有效的光谱分析工具提取出了实际的高光谱图像的地物光谱的吸收峰参数。
