A missing texture reconstruction method based on an error reduction (ER) algorithm, including a novel estimation scheme of Fourier transform magnitudes is presented in this brief. In our method, Fourier transform magnitude is estimated for a target patch including missing areas, and the missing intensities are estimated by retrieving its phase based on the ER algorithm. Specifically, by monitoring errors converged in the ER algorithm, known patches whose Fourier transform magnitudes are similar to that of the target patch are selected from the target image. In the second approach, the Fourier transform magnitude of the target patch is estimated from those of the selected known patches and their corresponding errors. Consequently, by using the ER algorithm, we can estimate both the Fourier transform magnitudes and phases to reconstruct the missing areas.
本文提出了一种基于误差减少(ER)算法的缺失纹理重建方法,包括一种新颖的傅里叶变换幅度估计方案。在我们的方法中,对包含缺失区域的目标块进行傅里叶变换幅度估计,并基于 ER 算法通过检索相位来估计缺失强度。具体来说,通过监测 ER 算法中的误差收敛,从目标图像中选择与目标块的傅里叶变换幅度相似的已知块。在第二种方法中,从所选的已知块及其相应的误差中估计目标块的傅里叶变换幅度。因此,通过使用 ER 算法,我们可以估计傅里叶变换幅度和相位来重建缺失区域。
