pnormalization

Performs normalization of image or graph.

pnormalization min max [-m mask] [im_in|-] [im_out|-]

pnormalization computes the normalization image's values or the graph's value between new values min et max.

If im_in is an image, pnormalization is applied on each pixel value:

pixel(im_out) = [(max - min) / (Max(im_in)-Min(im_in))] * pixel(im_in)
              + [(min*Max(im_in) - max*Min(im_in)) / (Max(im_in)-Min(im_in))];

For color or multispectral image, the normalization is computed separately on each band.

The output image im_out is of the same type as im_in.

If im_in is a graph then the new graph im_out is built with the normalization of each node value.

min and max are real values. Their values must be in the value domain defined by the input object type (eg., 0..255 for Uchar image, ...)

Returns SUCCESS or FAILURE.

Normalizes tangram.pan pixel between 10 and 234:

   pnormalization 10 234 tangram.pan a.pan

Errc PNormalization( const Img2duc &im_in, Img2duc &im_out, Uchar min, Uchar max );
