WebOct 12, 2024 · The texture aspect ratio of the surface Str is the ratio of the fastest to slowest decay to the correlation length 0.2. It is used to identify texture strength, i.e. uniformity of the texture aspect. Figure 1.3 shows isotropic surface and its autocorrelation function, but Fig. 1.4 shows anisotropic surface with its autocorrelation function. WebIn principle, the texture aspect ratio has a value between 0 and 1. For a surface with a dominant lay, the parameters will tend towards 0.00, whereas a spatially isotropic texture will result in a Str value of 1.00. If the autocorrelation for some direction does not decay below 20% or 37% the associated parameters will not be reported.
