  In order to extract the texture characteristic of a machined surface,a novel approach for extracting feature of gray image was proposed using waveletpacket transform and singularity value decomposition. The waveletpacket transform and the singularity value decomposition arithmetic were introduced.

  为提取机加工表面的纹理特征,提出利用小波包变换和奇异值分解提取灰度图像特征的新方法,给出了小波包变换算法及奇异值分解算法,依据矩阵奇异值特征向量的均值和方差分别定义了灰度图像的特征参数k1和k2,并探讨了特征参数与表面纹理之间的关系。
