Reconstructed HR images for different noise levels. Top row: one bicubic-interpolated LR image with up-sampling factor equal to 3 for each noise level, the noise variances are 0, 10, 20, 30, 40, and 50 respectively from left to right. Bottom row: corresponding final HR images reconstructed by OSR with up-sampling factor equal to 3 for each noise level
