摘要： A method is provided for decoding a data stream representing an object with at least three dimensions, associated with a basic mesh including of an assembly of facets defined by an assembly of vertices and ridges, and with wavelet coefficients corresponding to the local modifications of the basic mesh, indexed each by a vertex of the basic mesh. For at least some wavelet coefficients of the data stream, the method includes the following steps: determining an orientation of a ridge bearing the vertex indexing the wavelet coefficients, called an orientation of the wavelet coefficient; and determining, based on the orientation, information for locating in the basic mesh at least one child of the wavelet coefficient, distinct locating rules being associated with each orientation, so as to extract a data stream of at least some of the wavelet coefficients, associated each with a locating information.

摘要： The invention relates to a method for the coding an object having at leas two dimensions which is associated with a basic mesh comprising a set of basic surfaces and with coefficients in a base of wavelets corresponding to local modifications to said basic mesh. The inventive method delivers a global data flow that can be used to reconstruct the object. According to the invention, said wavelet coefficients are partitioned into at least two disjoint subsets each of which is encoded independently. Subsequently, positional data are inserted by the method into the global data flow which can be used to locate wavelet coefficients relative to a portion of the object in said global data flow, in such a way to enable a selective reconstruct of said portion using the coefficients of at least one said subsets.

摘要： The disclosure relates to a method of coding at least one still or animated image, in which said image is associated with (i) a basic mesh formed by a set of faces that are defined by a set of vertices and edges and (ii) coefficients in a base of wavelets corresponding to local modifications to the basic mesh, known as wavelet coefficients, wherein the coded data rate is controlled. The method includes the following steps: controlling a first rate of data representative of a basic mesh that meets a first rate criterion; controlling a second rate of data representative of wavelet coefficients according to a second rate criterion; and finally optimizing the coded data rate by controlling the quantification characteristics of the selected wavelet coefficients.

摘要： A method is provided for coding a source mesh (M) representing a three-dimensional object or a scene, using a simple mesh (M0) having a limited number of facets, each defined by vertices and edges, and coefficients in a base of wavelets, corresponding to local modifications of the simple mesh (M0), and making it possible, at each instant, to determine a function of parameterization of the mesh. The method includes a step to eliminate the effect of at least one wavelet coefficient (d; d1, . . . , dn) verifying at least one criterion of non-essentiality, so as to give a partial mesh (M′), corresponding to a partial representation of the source mesh (M).
