Abstract :
The main idea of the paper is to replace the covariance matrix involved in TUCKALS3 algorithm with the fourth order cumulant slice matrix of the data tensor n-mode vectors in order to eliminate the Gaussian components of the additive noise. The good qualitative results of this new multi-mode filtering method are shown in the case of correlated noise reduction in a color image and a polarized seismic wave, modelled by third order tensors.
