Image Reconstruction from Multiscale Singular Points Based on the Dual-Tree Complex Wavelet Transform

<div>Comparison of three probability density function (PDF) candidates: (a) original image; (b–d) curve fitting for the inverse Gaussian distribution (IGD), Gaussian mixture model (GMM), and mixture Rayleigh distribution (MRD), respectively. The histograms are taken from the image “Peppers,” with a scale index of 3 and an orientation of +75°.</div>
