Abstract :
An adaptive filter for video sequence super resolution reconstruction is proposed based on weighted least square and total variation regularization. We thoroughly study the motion compensation matrix and weighted matrix, and deduce the recursive filter formula. Experimental results demonstrate the proposed method to be adaptive and robust.
