In a method for evaluating porosity distribution within a porous article such as a crimped filter, a tobacco plug, or a cigarette, a digital image is obtained of a transverse area of the article and a pore area fraction is determined for each of a plurality of identically dimensioned sub-areas of the transverse area of the article. This provides a plurality of pore area fractions. The plurality of pore area fractions allow the evaluation of a local porosity distribution within the transverse area of the porous article. Each sub-area within which a pore area fraction is calculated overlaps with at least one adjacent sub-area by between 10% and 95%. The method for quantitatively evaluating porosity distribution may be used to control a process for manufacturing the porous article.
