Wavelet

Wavelets are mathematical functions used to analyze and represent data, especially signals or images, by breaking them down into different scales or resolutions. Unlike traditional methods that look at data as a whole, wavelets focus on local features, capturing both overall trends and fine details simultaneously. This makes them useful for tasks like image compression, noise reduction, and feature detection, providing a flexible way to understand complex information efficiently. In essence, wavelets act like smart filters that dissect data into meaningful parts at various levels of detail.
