IUWT

IUWT.jl contains a Julia implementation of the second generation Isotropic Undecimated Wavelet Transform (IUWT):

J.-L. Starck, J. Fadili, and F. Murtagh, “The Undecimated Wavelet Decomposition and its Reconstruction,” Image Processing, IEEE Transactions on, vol. 16, no. 2, pp. 297–309, 2007.

• iuwt_decomp() and iuwt_recomp() are a transcription of this Python code.
• iuwt_adj() implements the adjoint operator of the IUWT transform.

Installation

import Pkg
Pkg.add("https://github.com/andferrari/IUWT.jl.git")

Usage

using IUWT
x = rand(128,128)
coef, c0 = iuwt_decomp(x, 7, store_c0 = true);
norm(x - iuwt_recomp(coef, 0, c0 = c0))
