Periodic plus smooth image decomposition

WebOct 14, 2024 · In this method, edge artifacts are reduced by subtracting a smooth background that solves Poisson's equation with boundary conditions set by the image's edges. Unlike the traditional windowed Fourier transforms, Periodic Plus Smooth Decomposition maintains sharp reciprocal lattice peaks from the image's entire field of … WebIn this method, edge artifacts are reduced by subtracting a smooth background that solves Poisson’s equation with boundary conditions set by the image’s edges.

WebJul 22, 2024 · A discrete image u is decomposed under the form u = p + s, where p is called the periodic component of u and s is the smooth component of u. The periodic component p looks like the original image u, except that its Discrete Fourier Transform avoids the classical "cross structure" artifact. WebSmooth Decomposition (P+S) method.

WebJan 1, 2024 · Near-field ptychography provides advantages over far-field ptychography that large field-of-view (FOV) can be imaged with fewer diffraction images, and with weaker requirements on the detector dynamic range and beam coherence, which has drawn attention recently. WebMoisan (2011) defines an additive image decomposition im = periodic + smooth where the periodic part shouldn't be too far from the original image. The periodic part can be used in frequency-domain analyses, to reduce the artifacts induced by non-periodicity. ez online filings reviews
