WebNov 12, 2024 · 8. ∙. share. We propose RIFE, a Real-time Intermediate Flow Estimation algorithm for Video Frame Interpolation (VFI). Most existing methods first estimate the bi-directional optical flows and then linearly combine them to approximate intermediate flows, leading to artifacts on motion boundaries. RIFE uses a neural network named IFNet that … WebJan 9, 2024 · The Rife algorithm [ 12] is proposed to solve the detection of single frequency sinusoidal signal buried in noise. It is to use the two spectral lines closest to the signal spectral line to estimate the signal frequency. The sampled signal can be expressed as follow. x (n\Delta t) = a \cdot {\text {e}}^ { {j (2\pi f_ {0} n\Delta t + \phi_ {0} )}}
