imagehomog not working for the image

[Addhi86]

Hello

I am trying to use imagehomog function from the toolbox but unfortunately, i am not getting the correct output
here is my code

 im = imread('cameraman.tif');
n = [0;0;-1];
d = Inf
   theta = 60*pi/180;

   R = [ 1     1           0 ;
       0  cos(theta) -sin(theta);
       0  sin(theta)  cos(theta)];

   t = [0;0;0];

  K=[300 0    0;
        0    300 0;
        0    0    1];

  H=K*R/K-1/d*K*t*n'*K;

 img=imagehomog((im),H','c');
 figure;imshow(img)

I get this at the output

Can you please suggest me how can i fix it?

Sorry but I haven't went into this project for more that 3years and it was a study project, hence I'm not maintaining it.
