Abstract

We present an experimental approach to measure of the roughness of the paper on the
real time based in the analysis of speckle pattern on the surface. The image formed by
speckle in the paper surface is considered as a texture, and therefore texture analysis
methods are suitable for the characterization of paper surface. The properties statistical
of this speckle pattern are used for estimation and quantification of roughness parameter
Ra and Rq. We applied digital image processing using statistics of second order,
specifically the gray level co-occurrence matrix (GLCM), so this method can be
considered as non-contact surface profiling method. The results are contrasted to
confocal microscopy, autocorrelation function and fringe projection.
