Median Filter Explained | Robust Signal Denoising
• Introduction to the Digital Signal Process...
Learn how to implement a median filter to smooth noisy signals and remove outliers effectively. This tutorial highlights the differences between the median and mean filters and demonstrates why the median filter is more robust against extreme values.
In this lecture, we explore the median filter, a non-linear filter used for signal denoising. The median is the middle value of a data sequence and is independent of outliers, making it ideal for noisy or skewed signals. The filter moves over a noisy signal, replacing each data point with the median of neighboring points, resulting in smooth outputs. We also compare the median filter with moving average filters to show their strengths and limitations.
