In [[image processing]], '''normalization''' is a process that changes the range of [[pixel]] intensity values. Applications include photographs with poor [[contrast (vision)|contrast]] due to glare, for example. Normalization is sometimes called contrast stretching. In more general fields of data processing, such as [[digital signal processing]], it is referred to as [[dynamic range]] expansion.
