| http://www.w3.org/ns/prov#value | - The threshold may comprise a threshold ???range??? rather than a single threshold value; if the total pixel error value falls below the range, a pixel is not ???fired???; if the value falls above the range, the pixel is fired; and if the value falls within the range, a randomnizing mechanism, such as look-up table, may be used to determine whether a pixel is fired.
