Method for automatic type-font recognition without prior knowledge of the text contents, utilizing a representation of the text document by desriptors

摘要

The document to be scanned is scanned at several directions of projection. From the scanning results, so-called descriptors are derived at different basic pattern types which are then allocated to an edge, which in each case has already been scanned, of a symbol in the original. After the arcs or edges thus produced have been completed, they are introduced into a process for further processing. IMAGE
