Mathematical transform is one of the important means in seismic exploration data processing methods, there must be mathematical transforms from solving mathematical models to compressingseismic data.

Each of its pixels is sensitive to specific incident angles and supplies a component of the mathematical operation called the Fourier Transform to produce an image about 20 pixels across.

When they turned these measurements into a series of waves using a mathematical trick called a Fourier transform, the waves increased in magnitude as their frequency decreased.
