In spite of a hundredfold decrease in the cost of relevant technologies, the role of document image processing systems is
gradually declining due to the transition to an on-line world. Nevertheless, in some high-volume applications, document
image processing software still saves millions of dollars by accelerating workflow, and similarly large savings could be
realized by more effective automation of the multitude of low-volume personal document conversions. While potential
cost savings, based on estimates of costs and values, are a driving force for new developments, quantifying such savings
is difficult. The most important trend is that the cost of computing resources for DIA is becoming insignificant compared
to the associated labor costs. An econometric treatment of document processing complements traditional performance
evaluation, which focuses on assessing the correctness of the results produced by document conversion software.
Researchers should look beyond the error rate for advancing both production and personal document conversion.
