International 2D Phase Unwrapping Algorithm

In the field of 3D reconstruction, this international 2D phase unwrapping algorithm represents a significant breakthrough. The implementation employs both quality-guided unwrapping (using weighted phase derivative variance calculations) and branch-cut methods to effectively convert 2D phase information into accurate 3D structural data. The MATLAB version provides interactive visualization tools for phase quality maps, while the C++ implementation optimizes computational efficiency through multithreaded processing and memory-mapped file handling. Researchers can leverage the algorithm's dual-language implementation - using MATLAB for rapid prototyping and C++ for production-scale processing - to achieve more efficient 3D surface reconstruction and morphological analysis. The code includes specialized functions for handling noise-resistant phase gradient estimation and residue charge balancing, making it particularly valuable for phase-based 3D scanning applications.
