摘要
图像配准是超分辨率图像重建的关键.提出了一种基于R滤波器的超分辨率图像重建的三步算法.第一步:对原图进行加窗模糊;第二步:根据全局运动模型配准,计算平移参数和旋转角度,对图像进行平移和旋转;第三步:把序列低分辨率图像配准到同一个坐标系中,重构高分辨率图像.实验表明,三步算法的配准精度和超分辨率图像重建效果较好.
Image registration is the key to super-resolution image reconstruction.A three-step registration algorithm for super-resolution images based on R filter is presented.The first step is to obfuscate the original image by adding windows.The second step is to revolve and translate the image by calculating translation parameters and rotation angle according to the requirement of the global motion model.The last step is to match image sequences of low resolution in the same coordinate system and to reconstruct the high resolution images.Experiment results show that matching accuracy and result of reconstructing super-resolution images are greatly improved.
