pmin

Computes minimum values between image or graph.

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

pmin computes the minimum 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 minimum 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 minimum is computed separately on each band.

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

Returns SUCCESS or FAILURE.

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

   pmin a.pan b.pan c.pan

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

Minimum entre valeurs d'images ou de graphes.
