11.65. ITK Rescale Intensity Image Filter
Linearly rescales the full intensity range of an image into a chosen output range.
Group (Subgroup)
ITKImageIntensity (ImageIntensity)
Description
This filter applies a linear transform that maps the full intensity range of the input image onto a user-specified output range. The smallest input value maps to Output Minimum, the largest input value maps to Output Maximum, and everything in between scales proportionally. It is the standard way to normalize an image to a fixed range (for example 0-255 for display, or 0-1 for downstream processing).
$$ \text{output} = (\text{input} - \text{inputMin}) \cdot \frac{\text{OutputMax} - \text{OutputMin}}{\text{inputMax} - \text{inputMin}} + \text{OutputMin} $$
The input minimum and maximum are detected automatically, so only the output range is set by the user. To stretch a chosen input window rather than the full range (clamping outside it), use ITK Intensity Windowing Image Filter.
Parameter Guidance
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.
