Abstract
A method of creating a wavelet decomposition of a collection of data values is disclosed, the method including the steps of performing an initial decomposition of the data values into a series of components having low frequency components, high frequency components and components having a mixture of high and low frequencies; determining a first number of coefficients of each of the components having a magnitude exceeding a predetermined component threshold; creating a decomposition of each of the components into a series of sub components having low frequency sub-components, high frequency sub-components and sub-components having a mixture of high and low frequencies; determining a second number of coefficients of each of the sub-components having a magnitude exceeding a predetermined sub-component threshold; utilizing the first number and the second number to determine if the component should be decomposed into sub-components; and where the decomposition proceeds, applying the previous steps to each of the sub-components to a predetermined level of decomposition.
