spectral class

The inter spectral redundancy and intra spectral redundancy can be eliminated mostly by multilevel clustering algorithm with quickly convergent K means classification and the method clearing redundancy at step through enhancing the intra class pixel redundancy.

多层次聚类无损压缩就是利用改进的K-means聚类算法具有快速收敛的特点，和利用分层次去冗余的方法来聚类，因此可最大限度消除残差冗余。

It is pointed out that the spectral class c is possibly originated from the nonhomogeneity of the source even if the internal absorption in the source is neglected.

指出，由于源本身的不均匀性即可产生c型谱（低频倒转），即使源本身是光学薄的，完全忽略其内吸收。
