When the sub-pixel displacement among low- resolution images (LR) is "0.5" unit pixel, current micro-displacement super-resolution (SR) method can reconstruct encouraging high-resolution images (HR). But if actual LR video images are processed in the same way, some severe motion blur will appear in the restored image. Because of the quality difference, a new selection method based on the relative displacements and included angles errors among the LR images is proposed. And we can choose the optimum gather of LR frames to reconstruct the best HR images by micro-displacement algorithm. In the end, the experiment proves that our new micro-displacement method is feasible.
