11.41. ITK Intensity Windowing Image Filter
Linearly stretches a chosen input intensity window into a target output range, clamping everything outside the window.
Group (Subgroup)
ITKImageIntensity (ImageIntensity)
Description
This filter remaps pixel intensities with a linear “window/level” transform, the operation behind most medical-image and CT contrast controls. Input values inside the window — between Window Minimum and Window Maximum — are stretched linearly to fill the output range Output Minimum to Output Maximum. Input values below the window are clamped to Output Minimum, and values above it are clamped to Output Maximum. It is commonly used for visualization and as a preprocessing step before segmentation.
To map the full input range automatically instead of a chosen window, use ITK Rescale Intensity Image Filter.
Parameter Guidance
Window Minimum / Window Maximum — the lower and upper bounds of the input intensity window of interest, in input intensity units. This window is what gets stretched.
Output Minimum / Output Maximum — the target output range, in output intensity units (defaults 0 and 255).
Required Input Sources
Operates on any scalar image — typically from Read Image, Read Images [3D Stack], or the output of a prior ITK image filter.
