which introduces readers to periodic and non-periodic signals. The second part is devoted to filtering, which is an important and commonly used application. The third part addresses more advanced topics, including the analysis of real-world non-stationary signals and data, e.g. structural fatigue, earthquakes, electro-encephalograms, birdsong, etc.

(Lynn et al., 1995). Seismic data have wider spatial coverage than well data; thus, fracture detection using seismic data be- comes important for practicality. Shear-wave splitting is very sensitive to fracture orientation and density. However, the high cost of acquiring multicomponent data makes this method ex- pensive to apply on a regular

strong interference [1]. For example, the Prony method is widely used for solving problems in such areas of science and technology as seismic, medicine, radiolocation [2-4]. In presented study, we carried out a comparative analysis of the Prony method and spatial filtering methods having high [5] and ultra-high resolution [6].

possible decompositions applicable to seismic data. A fundamental characteristic of seismic data is non-stationarity. In 1-D (time dimension), seismic data are nonstationary because of wave-attenuation effects. In 2-D and 3-D (time and space dimensions), non-stationarity is manifested by variable slopes of seismic events.

Development of a New Method of Crack Modeling and Prediction

Median Filtering: Median filtering operation replaces a pixel by the median of all the neighboring pixels in an NxN window (N is always odd number). This is a nonlinear process and it reduces impulsive noise from an image without distorting the edges too much. 3. Illumination Equalization: This involve the application of Global-Local Adaptive

They can be measured more accurately by first decomposing time-lapse seismic images into discrete frequency components using the local time-frequency

Potential of Prony and Phase Decompositions for Reservoir

Prony Decomposition (Prony, 1795) is a unique signal decomposition that takes into account seismic wave attenuation/damping (Q-1) as well as phase, frequency and time. The Q-factor retrieved from the seismic data through Prony Decomposition can thus be used to map seismic attenuations. Since seismic waves

Sassa [1935], it has been well recognized that seismic signals associated with volcanic activity are character- ized by a wide variety of signatures. Attempts at clas- sifying these signals have been based on their wave- form signatures [e.g., Minakami, 1974]. Although de- tailed classification is possible, these types of signals

Therefore, the method can be called Prony filtration. Its closest analogue is a bandpass filtration. However, Prony filtration method provides higher resolution of

Moreover, obtaining zi as the roots of q(z) is also a challenging task to perform when (1) is perturbed by noise. More robust approaches have been proposed by exploiting the
