Wavelet packet analysis

Wavelet packet analysis is a method used to analyze complex signals and data by breaking them down into different frequency components. Imagine it like a musical piece that can be separated into various instruments; each instrument plays a distinct role. This analysis allows us to capture both the details and the overall trends in the data. It’s particularly useful in applications like image compression, noise reduction, and even in financial data analysis, providing insights that traditional methods might miss by focusing too narrowly on either high or low frequencies.
