A Laplacian pyramid is very similar to a Gaussian pyramid but saves the difference image of the blurred versions between each levels. Only the smallest level is not a difference image, to enable reconstruction of the high resolution image using the difference images on higher levels. This technique can be used in [[image compression]].<ref>{{cite journal | last1 = Burt | first1 = Peter J. | last2 = Adelson | first2 = Edward H. | year = 1983 | title = The Laplacian Pyramid as a Compact Image Code | url = http://persci.mit.edu/pub_pdfs/pyramid83.pdf | format = PDF | journal = IEEE Transactions on Communications | volume = 31| issue = | pages = 532–540| doi = 10.1109/TCOM.1983.1095851 }}</ref>
