Summary
The projection onto convex sets (POCS) interpolation method is well-known to interpolate the randomly sampled and aliased seismic data in geophysical community. To manipulate the thresholding step in this method with ease, we suggest using a percentage thresholding scheme. To combat the spectral leakage, we proposed to employe a redundant DFT frame by excessive zero-padding to exploit the Fourier domain sparsity. Empirically, double excessive zero-padding and less than 20% Fourier coefficients are enough to obtain a satisfying result, supported by the theory of spectral compressive sensing.
