👉 Wavelet is a mathematical technique used to analyze and transform data in a discrete domain, such as time or frequency. It was first introduced by Yves Cornulier in 1960s and has since become one of the most widely used tools for signal processing and image analysis. Wavelets are an extension of Fourier transforms that allow for the decomposition of signals into their frequency components, which can be useful in various applications such as image compression, speech recognition, and audio enhancement. They are
