The main aim of this contribution is comparison of method for evaluation of nonwovens surface uniformity based on the data in the form of rectangular arrays (quadrat method)。 These data can be obtained from digital images where the variation of mass is characterizes by the variation of grey level image。 The evaluation of uniformity is based on the variation coefficient model, ANOVA model and spatial descriptors of irregularity
