Seminar - Seismic texture attributes from local 2D Fourier spectra

We present a new approach to estimate frequency-based texture attributes from the local 2D Fourier spectrum. A set of new attributes is derived tailored to highlight near-horisontal layers, steep-dipping layers, and areas without any dominant orientation. Their suitability for discriminating between salt structures and layered structures with arbitrary dip is discussed, and the best attributes are used in an automatic segmentation algorithm that finds a smooth, continuous border between the salt structure and the surrounding areas. The results correspond very well with a manually interpreted contour.
