Re: enhance pencil sketch
try -auto-level or -contrast-stretch
convert 01.JPG -auto-level result1.jpg
the above may not be enough. If that is the case then try
convert 01.JPG -contrast-stretch XX% result2.jpg
where XX is some percent. I tried 1%, but you may want more or less.
see http://www.imagemagick.org/Usage/color_mods/ for more details on various types of contrast and brightness changes.
