proportionally spaced font Also known as a variable pitch font. Typeface in which each

character takes up an amount of horizontal space consistent

with its relative physical width, i.e. an “i” needs less space

than a “w.” Times Roman and Helvetica are two common

proportionally spaced typefaces. Compare with monospaced

font.

recognition accuracy A measure of the degree to which OCR output conforms to

the individual characters in the input document. Recognition

accuracy is a percentage expression of the number of correct

character identifications in relation to the total number of

characters in the page or document. This measure is often

used as the primary criterion in evaluating OCR performance,

even though it does not account for layout analysis errors.

Compare with

throughput.
