Detailed Description

ImageViz SoRescaleIntensityProcessing engine

The SoRescaleIntensityProcessing engine performs a linear scaling of the gray level values of an image.

This engine performs a linear scaling of the gray level values of an image to a user-specified interval. It may be applied to images with a gray level range other than [0, 255], and for short or floating point images. In Figure , the input gray levels of interest are in the user-specified interval [a, b], and the output range is the interval [c, d].

The normalize transformation

The input image is I, and the output image is O. Let [a, b] be the input range and [c, d] the output range, then:

\[\begin{array}{ll} O(n,m)=c & ~\mbox{if $I(n,m) \leq a$}\\ O(n,m)=\left(\frac{d-c}{b-a}\right)(I(n,m)-a)+c & ~\mbox{if $a < I(n,m) \leq b$}\\ O(n,m)=d & ~\mbox{if $I(n,m) > b$}\end{array}\]
