-1 CCD Multi-view Images

Objective As the deformation among multi-view images from the Chang’E-1CCD is non-rigid,giventhe non-planarity of the moon surface,the traditional methods based on the affine transform model arenot suitable for super-resolution correction.For this reason,a new optical flow based super-resolutionframework is proposed.In the framework,the BTV method is employed to estimate a high resolutionimage iteratively.The initial values for a high resolution image are generated by all multi-view imagesthat are registered by optical flow,while the optical flow fields are updated each iteration.Experimen-tal results show that the proposed method performs better for the super-resolution of Chang’E-1CCDmulti-view images than affine transform based methods.The resolution of the reconstructed image isgreatly improved and more details are visible without ringing-effects.
