Definition
Diese Klassifikationsstelle umfasst:(Für diese Definition ist die deutsche Übersetzung noch nicht abgeschlossen)
Document analysis, understanding and recognition of document images, involving the analysis of the document content, such as analysis of the geometrical or logical structure. Different types of documents can be involved, such as technical drawings, geographical maps, postal images, e.g. labels on parcels, addresses on postal envelopes.
Examples
Identification of the text region of a document after its skew correction
Extraction of image key points, considering them as nodes and constructing a graph representation by connecting with edges the neighbouring nodes; the graph-based representation is later used for document matching.
