A device for identifying at least one article within an image of a document, the document including plural articles, with each article including one or more objects. The device performs a first step in which the image is analyzed as to its layout to distinguish text blocks, titles, photographs and graphic elements. In a second step, the device assembles objects into groups by successive application of rules concerning their type and their mutual positioning. The image is displayed on a screen and an operator can select an article, can have the objects automatically re-arranged by the device in a form specified by him, and can have the article printed separately from the other articles in the document.

An apparatus and method for syntactic signal analysis which is suitable for processing signals which deviate, within a freely selected margin, from a set of signals predetermined by a grammar, the apparatus being provided with a feature unification mechanism which detects violations of features, and an adaptive threshold mechanism coupled thereto. The feature unification mechanism, which processes the features in groups so that rapid processing is obtained, determines a violation score, thus providing a measure of the deviation of the analyzed signal from the set of signals predetermined by the grammar and indicates what elements of the signal are not satisfactory so that these can be corrected if necessary. The adaptive threshold mechanism enables a number of analyses to be delivered each having a violation score, so that on the basis thereof, in combination with other factors which may be available, it is possible to select the best analysis. The apparatus is applicable to signal correction, signal verification and signal recognition.
