imnormalize

PURPOSE ^

Various ways to normalize a (multidimensional) image.

SYNOPSIS ^

function X = imnormalize( X, flag )

DESCRIPTION ^

 Various ways to normalize a (multidimensional) image.

 Sets image X to have zero mean and unit variance (if flag==1). 
 Sets image X to range in [0,1] (if flag==2). 
 Sets image X to have zero mean (if flag==3). 
 Sets image X to have zero mean and unit magnitude (if flag==4). 

 X may have arbitrary dimension (ie an image or video, etc).  X is treated as a vector of
 pixel values.  Hence, the mean of X is the average pixel value, and likewise the
 standard deviation is the std of the pixels from the mean pixel.

 INPUTS
   X       - n dimensional array to standardize
   flag    - [optional] determines normalization procedure

 OUTPUTS
   X       - X after normalization.
