Method For the Encoding of Wavelet-Encoded Images With Bit Rate Control, Corresponding Encoding Device and Computer Program |
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.
