Abstract
Method for determining at least one wavelet coefficient W(τ) of a wavelet transform of a signal in which the mother wavelet of the transform has a support subdivided into J≧1 intervals bound by (J+1) extremity points, and is defined by a polynomial of a maximum level N≧1 on each interval. The method includes calculating all or some of the primitives of the signal of order k between 2 and N+1, at least at (J+1) points corresponding to extremity points of the intervals of the wavelet support dilated by a factor of s and translated by a time τ; calculating the convolution of said or each primitive sampled in this way with a respective succession of (J+1) coefficients C(s), dependent upon said wavelet; and determining the wavelet coefficient by calculating a linear combination of convolutions. Steps a) to c) are implemented by a processor configured or programmed in an appropriate manner.
