Resource Overview
LWT Lifting Wavelet Decomposition 1-D - A MATLAB program that performs one-dimensional lifting wavelet decomposition using specified lifted wavelets, featuring customizable wavelet types and implementation of the lifting scheme algorithm through prediction and update steps.
Detailed Documentation
To enhance the performance of the wavelet transform program, we utilize the %LWT Lifting Wavelet Decomposition 1-D% function. LWT is a MATLAB-based program designed for one-dimensional wavelet transformation that operates according to specific lifted wavelets specified by the user. The implementation follows the lifting scheme methodology, which involves three key stages: splitting the signal into even and odd samples, applying prediction filters to approximate odd samples from even ones, and using update filters to maintain signal properties. This approach allows for in-place computations and efficient memory usage while supporting custom wavelet designs through modular filter components.
