WebThe first-order wave excitation force due to the incident and diffraction waves are calculated using the transfer function, i.e. (3) F 1 s t W (t) = R e {∑ i = 1 N [H W (ω i) A i e i (ω i t + φ i)]} where ω i, φ i, A i are respectively the frequency, phase, and amplitude of the ith component wave, H W (ω i) denotes the wave force ... WebNov 9, 2024 · 5 Conclusion. In this paper, we develop a new perspective for exposure correction with spatial-frequency information interaction in the spatial and frequency domain. We propose a deep Fourier-based Exposure Correction network (FECNet), which consists of two sub-networks: amplitude sub-network and phase sub-network.

Phase correlation is an approach to estimate the relative translative offset between two similar images (digital image correlation) or other data sets. It is commonly used in image registration and relies on a frequency-domain representation of the data, usually calculated by fast Fourier … See more The following image demonstrates the usage of phase correlation to determine relative translative movement between two images corrupted by independent Gaussian noise. The image was translated by (30,33) pixels. … See more Phase correlation is the preferred method for television standards conversion, as it leaves the fewest artifacts.
