I am getting the following error in the program of IMAGE MOSAIC USING SIFT ALGORITHM. Can anyone please help me out with the same? Also the matrix H is going infinite, what is the reason for that? Is there any input image restriction in the program?

please help me out in the following error I am getting, in the maketform function of MATLAB.

H =

   Inf   NaN   NaN
   NaN   NaN   NaN
   NaN   NaN   NaN

Error using maketform>validate_matrix (line 301) All elements of A must be finite.

Error in maketform>projective (line 236) A = validate_matrix( A, 'projective' );

Error in maketform (line 129) t = feval(fcn,varargin{2:end});

Error in imMosaic (line 17) tform = maketform('projective',H');

Error in main (line 12) img0 = imMosaic(img2,img1,1);

maketform is used in the ImMosaic is "tform = maketform('projective',H');".........

and ImMosaic is used in main is "img0 = imMosaic(img2,img1,1);".......
