<p>You can find Moire Pattern in <a href="https://docs.opencv.org/3.0-beta/doc/py_tutorials/py_imgproc/py_transforms/py_fourier_transform/py_fourier_transform.html" rel="nofollow noreferrer">Fourier transformed</a> image.</p>

<p>If you want to remove it, apply median filter and inverse Fourier transform.</p>

<p>See <a href="https://arxiv.org/ftp/arxiv/papers/1701/1701.09037.pdf" rel="nofollow noreferrer">this</a> paper.</p>
