Fei Feng, Xin Jia, Sheng Wei Bo, Lu Zhao · Applied Mechanics and Materials · 2014
Aiming at the limitations of traditional wavelet de-noising, multi-wavelet can possess symmetry, orthogonality, short support and high order vanish moments. However traditional single wavelet cannot possess all these properties at the same time. Analyze the principles of multi-wavelet method and the algorithm for image de-noising. The results prove that, multi-wavelet prior knowledge requirements for image signal is low, the suppression of noise interference at the same time. But it can preserve a more complete the useful signal.
