Phase and amplitude tracking for seismic event separation
We have developed a method to decompose seismic records into atomic events, each defined by a smooth phase function and a smooth amplitude function. This decomposition is intrinsically nonlinear and calls for a nonconvex least-squares optimization formulation, along the lines of full-waveform inversion. To overcome the lack of convexity, we have developed an iterative refinement-expansion schem...
متن کاملA short note on phase and amplitude tracking for seismic event separation
We propose a method for decomposing a seismic record into atomic events defined by a smooth phase and a smooth amplitude. The method uses an iterative refinement-expansion tracking scheme to minimize the highly nonconvex objective function. We demonstrate the proposed method on a noisy synthetic record from the shallow Marmousi model. Finally, we show an application of our method to low frequen...
متن کاملA method for event-related phase/amplitude coupling
Phase/amplitude coupling (PAC) is emerging as an important electrophysiological measure of local and long-distance neuronal communication. Current techniques for calculating PAC provide a numerical index that represents an average value across an arbitrarily long time period. This requires researchers to rely on block design experiments and temporal concatenation at the cost of the sub-second t...
متن کاملChinese Event Identification and Tracking Using Two Phase Clustering Algorithm
In this paper, two phase clustering algorithm is adopted to identify and track event. The first phase clustering is incremental clustering algorithm, and the new event will be identified. The second phase clustering is refined clustering algorithm, and the new event will be group and tracking. Experimental result shows that event identification and tracking using two phase clustering algorithm ...
متن کاملFuzzy logic for seismic waves separation
This work addresses the problem of signal separation for 2-Dimensional spaces. Instead of resorting to statistical properties of the signals, this work treats the problem as one of image segmentation. Variants of known fuzzy classifiers are studied and compared with existing techniques, as the Unsupervised Maximum Likelihood (MLU) classifier or the watershed technique. The goal is the separatio...
