What is smoothing filtering?

Smoothing Spatial Filter: Smoothing filter is used for blurring and noise reduction in the image. Blurring is pre-processing steps for removal of small details and Noise Reduction is accomplished by blurring.

How do you smooth out a signal?

The easiest way to smooth a signal is by moving window average. A more advanced way is to use a Savitzky-Golay filter.
