The experiment results show that this PCA algorithm can get the same compression ratio as the KLT algorithm with low complexity.

实验结果表明，该方法完全可以达到与K-L变换相当的压缩效果。

KLT is used to remove the correlation of spectral redundancy as one-dimensional (1d) linear transform, and SFCVQ coding is applied to enhance compression ratio.

KL变换作为一维线性变换被用于消除一维(1d)谱冗余，且SFCVQ编码被应用于提高压缩比。
