The Laplacian pyramid decomposition image fusion algorithm serves as a widely adopted method for image processing applications. This implementation utilizes MATLAB programming language and structures the algorithm into three distinct decomposition levels. The algorithm operates by first constructing Gaussian and Laplacian pyramids through iterative downsampling and differencing operations, then applying fusion rules at each pyramid level, and finally reconstructing the fused image using pyramid recombination. This multi-scale approach enables superior image processing and fusion capabilities, producing enhanced clarity and accuracy in the final output. Key MATLAB functions employed include `impyramid` for pyramid construction and `imfuse` for fusion operations, with custom weighting strategies applied at different decomposition levels to optimize feature preservation.
