We operation is not perfect, but some image blurring occurs. show that with a slight modification of the original Gaussian The difference between the original and the interpolated pyramid a decomposition algorithm is yielded, which has images gives Laplacian pyramid. In image coding and Gaussian pyramid reduce and expand operations with a perfect transmission applications the Laplacian pyramid operation reconstruction property. The method can be applied to multiresis frequently used to generate the exact reconstruction.
