Some years ago I saw an advertisement from a small seismic processing
contractor. It was in Leading Edge or First Break I think.
They were claiming they had a new noise attenuation algorithm.
The algorithm involed taking the quadrature trace of the input, so
that marrying the quadrature trace to original gives you a 2D
helical trajectory instead of 1D wiggle trace. And then because
you now had a 2D signal, you could remove random noise better.
It sounded like like bull**** to me, but it stuck in my mind.
I no longer have a stack of old magazines to search through.
Has anybody heard of an algorithm like this?
If so, who concocted it, and where did they publish it?
