Scalar fields\Bilateral filter

Menu / Icon

This tool is accessible via the 'Edit > Scalar fields > Bilateral filter' menu.

Description

Smooths a scalar field by applying a bilateral filter.

CloudCompare will first ask for the two parameters of the filter:

• spatial sigma: the Normal distribution variance for the spatial part of the filter
• scalar sigma: the Normal distribution variance for the scalar part of the filter

Edit > Scalar Fields > Bilateral filter dialog

Edit > Scalar Fields > Gaussian and Bilateral filters

The bilateral filter tends to preserve the strong edges better.

Note: a new scalar field is generated (i.e. the original scalar field is not overwritten).
