image processing - What Is the Bilateral Filter Category: LPF, HPF, BPF or BSF?



I`m reading about Bilateral filter with images, I knew that it uses Gaussian filter (which is a LPF) as a domain filter plus a range filter and it is used to preserve edges(high freq component).


Can we consider Bilateral filter as a LPF ? .


I searched some articles: 1- Which approach is better for decomposing a image into high frequency and low frequency component?


The answer was that bilateral filter attenuates ""medium frequency "


2- How to Extract High Frequency and Low Frequency Component Using Bilateral Filter?


The answer was to consider bilateral filter as a LPF.
