function y = imnormalize(x)
%IMNORMALIZE Normalize image values.
%  Y = IMNORMALIZE(X) linearly transforms the intensity values of the image
%  X to tightly cover the range [0,1]. If X has more than one channel, the
%  channels are handled as one and normalized using the same transform.

maxval = max(x(:));
