In kroemerlab/MorphR: MorphR

Image normalization with automated histogram adjustment

Description

Normalize image pixel intensities between 0 and 1

Usage

autoNormalize(
  x,
  inputRange,
  autoRange = T,
  RangeOnly = F,
  separate = T,
  step = 5 * 10^-3
)

Arguments

x	An array, or a 2D/3D matrix
inputRange	The targeted min and max pixel intensities
autoRange	A boolean indicating if inputRange should be calculated automatically
RangeOnly	If set to true, only calculated ranges are returned
separate	Shall image frames normalized separately ?
step	A numeric value, indicating probs from quantile option for inputRange automated calculation

Value

An array, a matrix or an image with values ranged from 0 to 1

Examples

m = replicate(100, rnorm(1,mean=0,sd=0.5))
m.norm = autoNormalize(m,autoRange=F);m.autoNorm = autoNormalize(m,autoRange=T,step=10**-1)
plot(density(m));points(density(m.norm),type='l',col='red');points(density(m.autoNorm),type='l',col='blue')
