Waveform Matching Algorithm for Eliminating EMD Endpoint Effects

This is a complete program I developed from scratch for eliminating endpoint effects in Empirical Mode Decomposition (EMD) using waveform matching techniques. The implementation includes detailed graphical visualizations and comprehensive documentation to facilitate user understanding. The program incorporates several advanced features such as automatic error detection and correction mechanisms, along with optimization options for the matching algorithm. Key technical components include boundary extension algorithms using waveform symmetry analysis and adaptive mirroring techniques to handle signal endpoints. The code implements intelligent peak-valley detection routines and spline interpolation methods for envelope construction. I've integrated performance optimization features that allow users to adjust matching thresholds and select different interpolation methods based on signal characteristics. This solution aims to help researchers effectively address endpoint effect issues in waveform matching applications while delivering improved decomposition results through robust algorithmic implementation.
