|Title:||Comprehensive Study of Parameters for Characterizing 3-D Surface Topography IV: Parameters for Characterizing Spatial and Hybrid Properties|
|Published:||November 01, 1994|
|Abstract:||This is the last part in a series of reports describing a comprehensive study of parameters to characterize three-dimensional surface topography. In conjunction with other parts of the report, this paper deals with parameters used to characterize spatial and hybrid properties of surface topography in three dimensions. Some statistical and signal processing techniques, e.g. two-dimensional autocorrelation function and spectral analysis, which are used to extract spatial and hybrid parameters, are introduced in the paper. Some spatial and hybrid parameters are recommended to be included in a primary set to save for a comprehensive characterization of surface topography in three dimensions. The definitions and algorithms of the parameters are given in the paper. The feasibility and significance of the parameters in characterizing surface topography in three dimensions are addressed by conducting experiments on a wide range of engineered surfaces. All discussions in the paper are based on theoretical and experimental justification.|
