Method for coding a mesh which represents a three dimensional object by wavelets, comprises a stage of suppressing wavelet coefficients which satisfy criteria of non-essentiality

摘要

A method of coding a source mesh (M) representing a three dimensional object uses a simple mesh (Mo) which has a reduced number of faces to facilitate simpler parameters. The method includes stages (11,12,13) of suppressing wavelet coefficients which satisfy non-essentiality criteria to provide a partial mesh (M') corresponding to a partial representation of the source mesh (M) Independent claims are made for equipment, systems and applications associated with the method
