中文摘要:
      针对高斯滤波、小波滤波等方法在三维表面形貌分析中存在的不足,提出了一种基于非下采样Contourlet 变换的三维表面形貌分析方法。 该方法是先通过非下采样 Contourlet 分解变换,将三维表面形貌分解成不同尺度的子带;然后根据滤波截止波长,确定表面形貌不同成分所属的分解子带层数;最后通过非下采样 Contourlet 重构变换,重构表面形貌的不同成分。 针对实际测量的三维表面形貌进行了分析,验证了该方法的有效性。
英文摘要:
      Aiming at the defects of the Gaussian filter and Wavelet filter, the nonsubsampled contourlet transform was applied in the 3 D surface topography evaluation. 3 D surface topography was divided into different scales subbands, and the subbands belonging to roughness, waviness and shape components were determined by the filter cut-off wavelength, and then the different components were generated by nonsubsampled contourlet inverse transform. At last, a actual measurement of 3 D surface topography were analyzed to verify the effectiveness of the proposed method.
