 Embedded Zerotrees of Wavelet transforms

Embedded Zerotrees of Wavelet Transforms (EZW) is a compression technique that leverages the properties of wavelet transforms to efficiently encode signals and images. It is particularly useful for compressing images due to its ability to exploit spatial redundancies and perceptual characteristics of human vision. ### Key Concepts: 1. **Wavelet Transform**: - Wavelet transforms decompose a signal or image into different frequency components at multiple scales.
