Curve-fitting compaction
Curve-fitting
compaction
is
data compaction
accomplished by
replacing
data
to be
stored
or
transmitted
with an
analytical expression
.
Examples
of
curve-fitting
compaction
consisting of
discretization
and then
interpolation
are:
Breaking
of a
continuous curve
into
a series
of
straight line
segments and specifying the
slope
,
intercept
, and range for each
segment
Using a
mathematical expression
, such as a
polynomial
or a
trigonometric function
, and a single point on the corresponding
curve
instead of storing or
transmitting
the entire
graphic
curve or a series of
points
on it.
