Abstract

The present invention relates to a method for processing mail to be returned to sender, according to which the extent of video-coding required when great quantities of mail sent by large mailers are to be returned to sender is reduced considerably. According to the invention similarities in the areas containing the senders' addresses are determined at the image level. In the case of mail where the address field images present a defined degree of similarity only one image is video-coded. The remaining mail displaying a defined degree of similarity to the video-coded item of mail is assigned to the corresponding sender.
