PROCESSIMAGES Procedure

NORMALIZE Statement

NORMALIZE <options>;

The NORMALIZE statement enables you to normalize the value range of an image. For more information about this statement, see the section NORMALIZE.

You can specify the following options:

ALPHA=number

specifies the lower boundary of the output range or the norm value, depending on the value of the TYPE= option. When TYPE=MINMAX, the ALPHA= option defines the minimum output pixel value. The default value of this option is most applicable to L2 normalization.

By default, ALPHA=1.

BETA=number

specifies the upper boundary of the output range and is used only when TYPE=MINMAX. The default value of the BETA= option is not typical for TYPE=MINMAX, and output pixels are expected to be normalized in the range [0, 1].

By default, BETA=0.

TYPE=INF |L1 |L2 |MINMAX

specifies the method to use in normalization.

By default, TYPE=MINMAX.
