(Min,+) Wavelets for Non-Linear Analysis
AbstractFor all function f: R^n --> R , one introduces (min,+) wavelets which are lower and upper hulls build from (min,+) analysis. One shows at theoretical level and on numerical applications for the Weierstrass functions, that (min,+) wavelets decomposition opens a non-linear branch to the multi-resolution analysis of a signal, in particular for the HГ¶lder exponents calculation and Empirical Mode Decomposition (EMD).
