ABSTRACT:
An automatic abstract character coding system automatically generates abstract coded characters from the text image of a document when the gross script-type is known to be, or is determined to be, a European type script. A connected component generating means generates connected components from the pixels comprising the text image. A spatial feature determining means generates a character cell surrounding one or more aligned connected component. A character-type classifying means converts the character cell to one of a plurality of abstract character codes.
