Appeal No. 96-1990
Application 07/536,910
set of generated samples always includes defects arising from the
two types of predetermined handwriting variations, the slope of
strokes and the size of subparts of characters. The appellant
correctly states (Br. at 8) that "Leung cannot and does not
permit the user to provide parameters which specify classes of
defects and thereby to define his own model for the defects."
(Emphasis in original.)
We reject the examiner’s statement (answer at 4) that
"[A]lthough the ‘user’ does not explicitly specify a ‘set of one
or more defect class parameters’, some ‘defect class parameters’
are implicitly specified because of the imperfect nature of
handwriting." We agree with the appellant that model symbols
inputted by a user are not defect class parameters specifying
particular classes of defects. The imperfect nature of
handwriting is a basis to conclude that the model symbols are not
perfect but is no reason to conclude that the symbols are defect
class parameters specifying particular classes of defects.
In short, in Leung the class of defective pixel
representation to be embodied in the set of generated samples is
predetermined and also fixed. Shearing operations are performed
to simulate different slopes in strokes and warping operations
