Image Projection for oriented images

 I = imread('img.jpg');
 udata = [0 1];  
 vdata = [0 1];  % input coordinate system
 tform = maketform('projective',[ 0 0;  1  0;  1  1; 0 1],...
                                       [-4 2; -8 -3; -3 -5; 6 3]);
 [B,xdata,ydata] = imtransform(I,tform,'bicubic','udata',udata,...
                                                        'vdata',vdata,...
                                                        'size',size(I),...
                                                        'fill',128);
   imshow(I,'XData',udata,'YData',vdata), axis on
   figure, imshow(B,'XData',xdata,'YData',ydata), axis on

this gives reverse operation what i am expecting. but i don't know how to choose the rows of projective in 'maketform', in order to reconstruct original image back.

This is just example,for different image how to choose the projective row in 'maketform'.
