Appeal No. 1998-0752
Application 08/389,096
waveform, representing one dimension of said character, to
provide a set of sample values of the amplitude of said
waveform;
calculating the amplitude ratio value of each sample of a
set by dividing each sample magnitude by the average sample
magnitude of the set;
determining the numerical difference between selected
ones of said sample amplitude ratio values with respect to an
adjacent sample amplitude ratio value to generate a set of
identifiers which determine whether said waveform has a rising
slope, a falling slope, or no change in slope between
respective ones of said selected ones of said sample amplitude
ratio values; and
comparing said set of identifiers with plural
predetermined sets of identifiers, each representing the
identity of a character, to recognize the character being
scanned.
