We propose a method to efficiently measure time shifts and scaling functions
between seismic images using amplitude-adjusted plane-wave destruction filters.
Plane-wave destruction can efficiently measure shifts of less than a few
samples, making this algorithm particularly effective for detecting small
shifts. Separating shifts and scales allows shifting functions to be measured
more accurately. When shifts are large, amplitude-adjusted plane-wave
destruction can also be used to refine shift estimates obtained by other
methods. The effectiveness of this algorithm in predicting shifting and
scaling functions is demonstrated by applying it to a synthetic trace and a
time-lapse field data example from the Cranfield CO
sequestration project.
