 Curvefitting compaction

Curvefitting compaction is data compaction accomplished by replacing data to be stored or transmitted with an analytical expression.
Examples of curvefitting 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.
