ICA (Independent Component Analysis) is a signal processing method implemented through MATLAB programming. It can decompose mixed signals into statistically independent components, effectively extracting key underlying information. ICA finds widespread applications across multiple domains including image processing, speech recognition, and biomedical engineering. When implementing ICA algorithms in MATLAB, developers typically utilize key functions like FastICA or JADE for blind source separation, applying techniques such as centering, whitening, and optimization algorithms to maximize non-Gaussianity. Through the application of ICA methodology, researchers can better understand and interpret complex signal structures, enabling deeper scientific investigation and analysis. The MATLAB implementation often involves matrix operations and statistical computations to separate independent components from observed mixed signals.
