Source Code for Second-Generation Lifting Wavelet Threshold Compression Algorithm

This source code implements a threshold-based compression algorithm using second-generation lifting wavelets. Key customizable parameters include decomposition levels, wavelet types, and threshold calculation formula coefficients for each level. The implementation converts low-frequency coefficients to hexadecimal format to facilitate further compression techniques like Huffman coding. The well-commented code demonstrates clear implementation logic, supports multiple wavelet families, and effectively illustrates second-generation wavelet concepts - making it particularly valuable for wavelet beginners.
