Smoothing From wiki In statistics and image processing,to smooth a data set is to create an approximating function that attempts to capture important patterns in the data,while leaving out noise or other fine-scale structures/rapid phenomena. In smoothing,the data points of a signal are modified so individual points (presumably because of noise)are reduced, and points that are lower than the adjacent points are increased leading to a smoother signal.
