Abstract
The goal of this work is the fast extraction of relevant information from document images. Examples of interesting information are the type of document (e.g. form, report, letter), the title of an article or the sender of a business letter, and a logo or figure on a page. The basic idea is to use non-textual cues from the document image before any OCR/ICR or word recognition is performed. The approach is based on a compact runlength representation of the binary image and allows a document type classification by white space analysis in a time comparable with the input of the compressed image. Graphics related information extraction needs approximately the same time.
