Title: Improved local pdf estimation in the wavelet domain for generalized lifting ; Authors: Rolon, J.C., Salembier, P., ; Researchers (PRC):, Salembier, P.

In this paper we introduce an adaptive local pdf estimation strategy for the construction of Generalized Lifting (GL) mappings in the wavelet domain.

Abstract: In this paper we introduce an adaptive local pdf estimation strategy for the construction of Generalized Lifting (GL) mappings in the wavelet domain.

Our approach consists in trying to estimate the local pdf of the wavelet coefficients conditioned to a context formed by neighboring coefficients. To this end, ...
