An analysis of simulated paper formations was conducted using the continuous wavelet transform. A series of simulated images with specific characteristics of grammage, flocculation and orientation were generated and analyzed using conventional and wavelet spectral analysis. Local spectral energy maps derived from wavelet transforms were used to study grammage features. The sensitivity of the wavelet analysis to variations in grammage, floc size, and structural anisotropy was determined. The response of the method to variation of formation as a function of position, or non-stationarity, was examined by testing images with controlled gradation of floe size. The ability to measure variation of orientation as a function of position was also demonstrated.
