Interpolation using wavelet bases
Alex Pentland · IEEE Transactions on Pattern Analysis and Machine Intelligence · 1994
Efficient solutions to regularization problems can be obtained using orthogonal wavelet bases for preconditioning. Good approximate solutions can be obtained in only two or three iterations, with each iteration requiring only O(n) operations and O(n) storage locations. Two- and three-dimensional examples are shown using both synthetic and real range data.>
