Abstract:
A method for dynamically reconstructing a representation of handwritten data expressible as a sequence of data points as a function of time, the method comprising the steps of:capturing a parametric representation of data handwritten on a digitizer tablet as a function of time;applying a process to said parametric representation a each data point to enhance said parametric representation as a function of time to obtain processed data points as a dynamic reconstruction including calculating values of data points of the dynamic reconstruction according to the following relationship:X.sub.i =X.sub.i -1+f.sub.x (x.sub.i -x.sub.i -1),Y.sub.i =Y.sub.i -1+f.sub.y (y.sub.i -y.sub.i -1),wherex.sub.i and y.sub.i over the range i=0 to i=N-1 is the discrete representation of a stroke,X.sub.1 and Y.sub.i over the range i=0 to i=N-1 is the discrete representation of a dynamic reconstruction of a stroke,f.sub.x and f.sub.y are functions representing the applied process and are given by:f.sub.x (x.sub.i -x.sub.i -1)=(x.sub.i -x.sub.i -1).sup.a,f.sub.y (y.sub.i -y.sub.i -1)=(y.sub.i -y.sub.i -1).sup.b,wherea is any real number excluding 0, 1, or -1,b is any real number excluding 0, 1, or -1; andN is the number of points; andsaving each said processed data point.
