【摘要】 提出了一种结合频域运动估计和迭代反投影的超分辨率图像重建算法。根据输入低分辨率序列图像各帧之间的傅立叶变换相位差,估计出每幅低分辨率图像相对于参考低分辨率图像的子象素位移;依据所得的子象素位移并结合迭代反投影算法,实现了超分辨率图像重建。实验结果表明,该算法是一种有效的超分辨率图像重建方法。更多还原

【Abstract】 An image super-resolution reconstruction method,which combines the frequency domain motion estimation and iterative back projection(IBP)algorithm,has been proposed.Based on the frequency domain phase difference among the low resolution images,the motion parameters between the reference LR image and other LR images are estimated.Combining the IBP algorithm and the estimated motion parameters,the super-resolution image is iteratively reconstructed.Experimental results demonstrate that the proposed method is effective.更多还原
