A new algorithm based on the projections onto convex sets method is used to smooth the discontinuities between speech frames. A two-dimensional extension of the Gabor time-frequency decomposition is also developed for image coding. Simulation examples are presented.viii, 28 leaves, illustrationsEnglishinfo:eu-repo/semantics/openAccessSpeech codingİmage codingTime-frequency dictionariesMatching pursuit algorithmTK7882.S65 G86 1994Speech processing systems.Thesis
