Obtained results were compared with those received after appliance of commonly-used algorithms. The effect of appliance of proposed procedures on surface topography parameters (from ISO 25178 standard) was taken into consideration. The following types of surface textureswere assessed: two-process plateau-honed cylinder liners, plateau-honed cylinder liners with additionally burnished dimples, turned piston skirts, grinded and/or isotropic topographies. It was assumed that envelope characteristics (envelope filtration) can provide results useful for assessments of deep and/or wide oil-reservoirs especially when they are edge located. Moreover, some near-valley areas of surface texture details can be less distorted when envelope filtering is accomplished. It was also found that closing and/or opening envelope filtration can be valuable for reduction of some surface topography measurement errors.}, type={Article}, title={Comparisons of envelope morphological filtering methods and various regular algorithms for surface texture analysis}, URL={http://journals.pan.pl/Content/116010/PDF/art03.pdf}, doi={10.24425/mms.2020.132772}, keywords={surface texture, surface topography measurement, envelope filter, morphological filtering, measurement errors}, }
