Wavelet Coefficients

Wavelet coefficients are numerical values that represent how much a signal or image contains specific patterns or details at different scales and locations. Imagine breaking down a complex picture into layers that highlight both broad shapes and fine details. The coefficients quantify these features: larger values indicate stronger presence of particular patterns at certain sizes and positions. This process helps analyze, compress, or denoise data efficiently by focusing on important features while reducing less significant information. Essentially, wavelet coefficients serve as a compact summary of a signal's structure across various levels of detail.
