C.L. Yu, Yubao Tang, Ching Y. Suen · 2002

Combined with pattern recognition techniques, DAL can be widely used in document analysis and understanding with very wide scopes including general newspaper articles, editorials, financial forms, advertisements, front page of magazine, etc. Bank cheques are employed as an example.>
