Seismic Wavelet Extraction Methods in Digital Seismic Data Processing

In digital seismic data processing, we can utilize either simulated annealing-based higher-order cumulant wavelet extraction methods or MATLAB-implemented seismic wavelet extraction approaches. These methods effectively extract useful information from seismic signals and facilitate processing and analysis of seismic data. The simulated annealing-based higher-order cumulant method employs optimization algorithms to accurately characterize seismic signal features through statistical moment analysis, typically implementing temperature-controlled probabilistic acceptance criteria and convergence parameters in the code structure. This approach provides enhanced precision in feature extraction through its sophisticated mathematical framework. MATLAB-based implementations offer greater flexibility and convenience, suitable for various types of seismic signals. Key functions may include wavelet transform algorithms, frequency domain analysis routines, and customizable parameter configurations that allow adaptation to different seismic data characteristics. The MATLAB environment enables rapid prototyping with built-in signal processing toolboxes and visualization capabilities. Therefore, when conducting digital seismic data processing, appropriate methods can be selected based on specific requirements to achieve optimal results, considering factors such as data complexity, computational resources, and desired accuracy levels.
