Abstract
An experimental printed-page reader that is easy to adapt to various languages is described. Changing the target language may involve simultaneous changes in symbol sets, typefaces, sizes of text, page layouts, linguistic contexts, and imaging defects. Our strategy has been to isolate the effects of these sources of variation within separate, independent engineering subsystems. In this way, we have been able to construct, with a minimum of manual effort, classifiers for arbitrary combinations of symbols, typefaces, sizes, and imaging defects. We have tried to rid the algorithms of all language-specific rules, relying instead on automatic learning from examples and generalized table-driven methods. For some tasks we have been able to avoid languagedependency altogether: for example, for geometric page layout analysis we have found a global-to-local strategy that requires no prior knowledge of the symbol set. We can exploit linguistic context, such as provided by dictionaries, through da...
