Algorithm 1

Our iterative SR algorithm.
Input:
  The observations ; The motion parameters ; The hyper-parameters ,
  ; The scale parameters ; The parameters .
Output:
  The HR image ;
(1) Use the Bicubic interpolation of the first LR image as initial value for the HR image.
(2) ;
(3) repeat
(4)  Compute by using (20) and (21);
(5)  Compute by using (22);
(6)  Compute by using (23) and (24);
(7)  Compute by using (25);
(8)  Compute by using (26) and (27);
(9)  Compute by using (14);
(10)  ;
(11) until convergence criterion is met
(12) Set .
