Intensity values linear scaling
Linearly scale the intensity values of an image to a specified range.
## S4 method for signature 'Image' normalize(object, separate=TRUE, ft=c(0,1), inputRange) ## S4 method for signature 'array' normalize(object, separate=TRUE, ft=c(0,1), inputRange)
object |
an |
separate |
if |
ft |
a numeric vector of 2 values, target minimum and maximum intensity values after normalization |
inputRange |
a numeric vector of 2 values, sets the range of the input intensity values; values exceeding this range are clipped |
normalize performs linear interpolation of the intensity values of an image to the specified range ft. If inputRange is not set the whole dynamic range of the image is used as input. By specifying inputRange the input intensity range of the image can be limited to [min, max]. Values exceeding this range are clipped, i.e. intensities lower/higher than min/max are set to min/max.
An Image object or an array, containing the transformed version
of object.
