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. % Ron Rubinstein % Computer Science Department % Technion, Haifa 32000 Israel % ronrubin@cs % % May 2004 maxval = max(x(:)); minval = min(x(:)); y = (x-minval) / (maxval-minval);
