We have developed a fast and robust algorithm for the extraction
of 3-D seismic attributes. The algorithm is based on the recursive
computation of the 3-D sliding-window Radon transform.
Considerable gain in computational efficiency has been achieved
with respect to existing algorithms. Field data results
demonstrate the effectiveness of the method for 3-D seismic
interpretation.
