A method for applying an operator to the first set of values is set forth and comprises the following steps: transforming the first set of values, on a wavelet/wavelet-packet basis, into a transformed vector (710); transforming a second set of values, on a wavelet/wavelet-packet basis, into a transformed matrix (720); performing a thresholding operation on the transformed matrix to obtain a processed transformed matrix (730); multiplying the transformed vector by the processed transformed matrix to obtain a product vector (740); and back-transforming, on a wavelet/wavelet-packet basis, the product vector (750). The thresholding operation may also be performed on the transformed vector. The techniques and apparatus of the invention can be employed in the following fields: processing and enhancement of audio and video information; processing of seismic and well logging information to obtain measurements and models of earth formations; medical imaging processing; optical processing: calculation of potentials and fluid flow; and computation of optimum design of structural parts. |
