Abstract

A method and an apparatus transport an article of mail. During a first decision-making process, an image of the article is generated and evaluated to generate a first vector. Further, a transport attribute is measured and stored together with the first vector. The transport of the article is continued on the basis of the measured transport attribute value. During a further decision-making process, an image of the article is generated and evaluated to generate a second vector. The transport attribute value is determined with the aid of the second vector. The transport of the article is continued on the basis of the stored and determined transport attribute value. The article is provided with an optically detectable element. The first vector is generated such that it contains that value assumed by the feature for the article if the surface of the article had already been provided with the optically detectable element.
