I tried to increase the quantum depth of the GraphicsMagick to 16bits. I downloaded the GraphicsMagick package from here. Here is the result for the version details and quantum depth result for gm version.
karthikeyan@karthikeyan:~$ gm version

Configured using the command:
./configure '--with-quantum-depth=16' '--enable-shared' '--disable-static' '--with-magick-plus-plus=yes'
So I went ahead to process images,assuming my graphicsmagick can handle 16 bits, but I am getting this error. Please help to resolve this:
karthikeyan@karthikeyan:~$ octave
octave:1> i = imread("/home/karthikeyan/Pictures/Wallpapers/f1376677896.jpg");
warning: your version of GraphicsMagick limits images to 8 bits per pixel

apt-getto install Octave? Is this the right way - http://askubuntu.com/questions/652004/ddg#670818 ? – karthikeyan Oct 02 '16 at 16:54
