This paper investigates the application of a new concept called the "overcomplete discrete wavelet transform" (ODWT) for image sequences compression. It has been demonstrated that: "The translated function with any integer multiple of the sampling pe

The efficiency of all zerotree coding algorithms relay on the "decaying spectrum" hypothesis: a wavelet coefficient within a certain frequency scale of a wavelet subband decomposition has a larger magnitude than all his descendants (coefficients situ

Enhancement of noisy data is a very challenging issue in many research and application areas. In the last years, nonlinear filters based on wavelet transforms have been shown to be very effective in removing noise without destroying the useful inform

In this paper we introduce a new coding method for image sequences, based on the concept of the "overcomplete discrete wavelet transform" (ODWT). Our main contribution can be stated as: "The translated function with any integer multiple of the sampli

Spectral analysis of stimuli in the excitation processes has revealed interesting correlations between macroscopical events (reflected in the excitation threshold of the nerve membrane) and microscopical events (reflected in electrical noise associat
