pmax

Performs maximum values between image or a graph.

pmax [-m mask] [im_in1|-] [im_in2|-] [im_out|-]

pmax computes the maximum values between inputs im_in1 and im_in2.

If im_in1 and im_in2 are images then the new image im_out is built with the maximum between pixel values of the two input images:

   if (pixel(im_in1) < pixel(im_in2))
   then pixel(im_out) = pixel(im_in2)
   else pixel(im_out) = pixel(im_in1)

The input image im_in1 and im_in2 must be of the same type, and the output image im_out is of the same type as the two input images.

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

If im_in is a graph then the new graph im_out is built with the maximum of values of nodes with the same index.

Returns SUCCESS or FAILURE.

Computes the maximum between pixels of the two images a.pan and b.pan:

   pmax a.pan b.pan c.pan

Errc PMax( const Img2duc &im_in1, const Img2duc &im_in2, Img2duc &im_out );

Maximum entre valeurs d'images ou de graphes.
