Image Fusion Using Laplacian Pyramid

The image fusion program employing Laplacian pyramid requires MATLAB versions newer than MATLAB 2009 to execute the image fusion functionality. Image fusion is a technique that combines multiple images into a single composite image, integrating distinct features from different source images to produce richer and clearer visual results. The Laplacian pyramid algorithm achieves fusion through multi-scale decomposition and reconstruction processes - first building Gaussian pyramids by progressively downsampling images, then computing Laplacian pyramids as difference maps between pyramid levels. This hierarchical approach efficiently blends image information across different scales, yielding superior fusion outcomes. Key MATLAB functions involved include impyramid for pyramid construction and imfuse for fusion operations. To ensure full utilization of the algorithm's performance capabilities and advanced functions, please verify that you are using MATLAB software newer than the 2009 release when performing image fusion tasks.
