SparseRepresentation

Wavelet compression of one seismic vintage. Thresholding the observed vintage fixes the leading coefficients; later calls reduce any vintage to those.

compress(data, th_mult=None)

Compress data (the masked grid, flattened). With th_mult the coefficients are thresholded and the leading indices (re)defined; without it the stored indices select them. Returns (compressed, wdec_rec).

reconstruct(wdec_rec)

The masked, flattened vintage rebuilt from the retained wavelet coefficients.
