In this paper, we propose a robust approach to super-resolution static sprite generation from multiple low-resolution images. Considering both short-term and long-term motion influences, a hybrid global motion estimation technique is first presented for sprite generation. An iterative super-resolution reconstruction algorithm is then proposed for the super-resolution sprite construction. This algorithm is robust to outliers and results in a sprite image with high visual quality. In addition, the generated super-resolution sprite can provide better reconstructed images than a conventional low-resolution sprite. Experimental results demonstrate the effectiveness of the proposed methods.
