INTERPOLATORY WAVELETS, Donoho, , 1992.These wavelets correspond to the interpolating subdivisionscheme as follows:δ 0,k ∈Starting the subdivision from the sequence { } k ZOn V 0 and refine to V l , in the limit l → ∞we will get what Donoho, (1992), calls the scaling function, orfundamental function of Deslauries and Dubuc, ϕ(x)From the construction, ϕ has compactsupporton[ − p +1,p −1]is symmetric around x=0 and is cardinal, in thesenseϕ( k)δo,= k ,k∈Doing translations and dilations of (x)ϕjk(x)we can define the interpolant of f(x) in any V j by:} k ∈ ZPjfZ∑(,kwhere { ϕj,k is a basis in V j .x)= fj, kϕj k( x)jϕ by =ϕ(2x−),k
