Histogram smoothing

When generating RGB images from multispectral data, histogram smoothing ensures that the intensity distributions used to define each color channel are free from spurious noise spikes. By smoothing the per-band histograms before averaging into red, green and blue channels, you obtain more balanced and visually coherent renderings without color artifacts caused by sensor variability or illumination changes.

Minimum number of bands for histogram smoothing

Found on the General tab of Workspace Settings.

This parameter defines the minimum number of spectral bands a dataset must contain before histogram smoothing is performed. It prevents unnecessary processing - and potential over-smoothing - on devices with limited band counts, such as typical multispectral systems or standard RGB cameras. Only when the band count meets or exceeds this threshold will smoothing be applied prior to channel averaging.
