The Bilateral Blur filter blurs an image while retaining areas of high contrast. As these contrast changes most commonly occur at edges, it makes the filter very useful both for noise reduction and for creating interesting stylistic effects.
This filter can be applied as a non-destructive, live filter.
The following settings can be adjusted on the vertical slider:
Radius—controls the size of the area sampled for the blur.
Tolerance—controls whether pixels are included within the blur based on the difference between tonal values of neighbouring pixels. At larger tolerance values, pixels with greater tonal differences will be included within the blur.The following settings can be adjusted on the context toolbar:
Apply—applies changes made.
Cancel—cancels changes made.
Split—enables the Before and After view. When toggled, it presents filter application side by side.
