MATLAB source code for implementing Laplacian pyramid-based image decomposition and fusion with algorithmic implementation details
Detailed Documentation
This MATLAB source code implements Laplacian pyramid-based image decomposition and fusion. The Laplacian pyramid is an image processing technique that decomposes an image into multiple-scale detail and coarse components, then reconstructs them through image fusion. The code implements Gaussian pyramid construction using imgaussfilt() or similar filtering functions, followed by Laplacian level generation through image subtraction between pyramid levels. Key functions include pyramid level generation, coefficient blending algorithms for fusion operations, and pyramid reconstruction using expand() and combine operations. This implementation provides detailed multiscale image processing capabilities, allowing comprehensive analysis and enhanced fusion results through weighted combination of pyramid coefficients across different frequency bands.
