i am facing lots of problems while running code for image stitching given at this link http://se.cs.ait.ac.th/cvwiki/matlab:tutorial:image_stitching_from_high-view_images_using_homography

may i get help regarding this type of problems here.

EDIT: Image stitching code fails with the following message:

??? Undefined function or variable 'x2'. Error in ==>compute_direct_homography at 26 amplified_x2=x2.*repmat([diagonal_ratio(x1,x2) diagonal_ratio(x1,x2) 1]',1,size(x2,2)); %assumption 1degree of lat and long =110,000 meters refer wiki Error in ==> project at 3 compute_direct_homography;
