An adaptive tree search algorithm with application to multiresolution based perceptive audio coding
N.G. Prelcic, Antonio Pena · 1996
Search algorithms for selecting signal decompositions based on the minimization of a cost functional have been proposed in the literature, in addition to several additive and non-additive information costs. We introduce a new cost function and a search algorithm built from a perceptual criterion. Their efficiency is demonstrated with results showing higher quality compressed audio signals than preliminary approaches at similar bit-rates.
