The implementation methodology for a CD-ROM English document database

Producing a database of scanned document images for development or evaluation of OCR and document image understanding algorithms is neither easy nor inexpensive. The authors first briefly describe the makeup of a database of scanned document images of scientific and technical documents written in English which are being produced in a CD-ROM format. Then, the authors concentrate on the implementation methodology used to prepare the database. The methodology gives the protocols for each step of the database preparation, and the error model used for the estimation of the ground-truth errors that may exist in the database is discussed
