IntensityExtrema

Computes basic minimum and maximum intensities of an image.

Access to parameter description

For an introduction: For an image $I$ This algorithm supports grayscale, color, multi-channel images, 3D volumes, and time series as inputs. The policy to manage the dimensions in each case can be defined with the splitResult parameter.
