Resolution enhancement of color video sequences

We propose a new multiframe algorithm to enhance the spatial resolution of frames in video sequences. Our technique specifically accounts for the possibility that motion estimation will be inaccurate and compensates for these inaccuracies. Experiments show that our multiframe enhancement algorithm yields perceptibly sharper enhanced images with significant signal-to-noise ratio (SNR) improvement over bilinear and cubic B-spline interpolation.
