How to crop image?

I want to crop the image in matlab, so the image just display the characters "*H 43 L*" and "*B 411 PJK*".

And the "*2 points*" and characters "*04.16 _*" in below are cropped.

Here is the images : <http://i1360.photobucket.com/albums/r649/farhat1s/cropfigure_zps100720e6.png>

and this one http://i1360.photobucket.com/albums/r649/farhat1s/cropfigure2_zps05089228.png

I want that the displayed objects is only object from the right side to the left side.

And here is my code..

   [labelled jml] = bwlabel(citra_fill);
   Iprops=regionprops(labelled,'BoundingBox','Image');
   a=~citra_fill;
   [f c]=find(a);
   lmaxc=max(c);lminc=min(c);
   lmaxf=max(f);lminf=min(f);
   imgn=a(lminf:lmaxf,lminc:lmaxc);%Crops image

Any suggestion?
