The article, for example a glass bottle, may exhibit at least one feature, in particular a defect, visible from outside the article, from among features of different types T1, . . . , Ti, . . . , Tn. In this process, acquisition of a digital image of the article is carried out, this image is processed so as to extract therefrom a region corresponding to this visible feature, the type of the visible feature is identified from among the various types Tl by calculating at least one discriminating parameter P1, . . . , Pj, . . . Pn characterizing the region, and the type of the feature is used to decide whether the quality of the article is adequate or inadequate. As appropriate, a reference parameter PR characterizing the region is calculated, this reference parameter PR is compared with a threshold parameter dependent on the type of the visible feature, and the result of this comparison is used to decide whether the quality of the article is adequate or inadequate.
