This paper introduces a new inpainting technique denominated Turbo inpainting. The algorithm modifies the K-clustering with singular value decomposition (K-SVD) inpainting method  to allow for iterative, progressive improvement. Turbo inpainting is composed of two separate blocks: inner inpainting and outer inpainting. The outer inpainting block… (More)
Traditional two-dimensional empirical mode decomposition (2D-EMD) algorithms generate multiple subband signals, each having the same size of the original signal. Thus, huge amounts of data to be stored may be generated. Moreover, the computational load is massive as the decomposition levels increase. This paper introduces a method to reduce the data… (More)
Undecimated and decimated multivariate empirical mode decomposition filter banks (MEMDFBs) are introduced in order to incorporate MEMD equipped with downsam-pling into any arbitrary tree structure and provide flexibility in the choice of frequency bands. Undecimated MEMDFBs show the same results as those of original MEMD for an octave tree structure. Since… (More)
We present an algorithm which performs data encryption by serially concatenating two transform stages. The outer stage uses one of the orthogonal matrices obtained from the singular value decomposition (SVD) of an arbitrary signal, such as white noise or the sum of cosines of different frequencies. The inner stage of encryption uses a fast, parallelized… (More)
This paper introduces a technique to build undecimated Multivariate Empirical Mode Decomposition Filter Banks (MEMDFBs) for arbitrary trees. The available option of undecimated MEMDFBs for arbitrary trees is achieved by exchanging assisting noise channels. An application for speech enhancement is also introduced.
This paper puts forward a new method to fuse infrared images using empirical mode decomposition (EMD) and inpainting algorithms. EMD is a non-parametric, data-driven analysis tool that decomposes non-linear, non-stationary signals into a set of signals denominated intrinsic mode functions (IMFs) and a residual. Fusion rules are set up to fuse the… (More)
