Abstract: The invention relates to an arithmetic encoding by bit planes (MSB, . . . , LSB), that comprises using tables of probability to have a 0 or 1 bit for encoding each bit plane. According to an embodiment of the invention, the probability tables are calculated dynamically for each signal frame based on a probability density model (Mod) corresponding to the distribution (H) of the signal (X) on each frame.

Abstract: The disclosure relates to a method for estimating the number of leader vectors with norm lp equal to rδp,d, of dimension d, having co-ordinates which are lower than, or equal to k. The method is characterized in that r p delta, d is determined by the sum of the results of a function T(Xi) for i varying between 1 and d, the function T(Xi) providing, for at least some of the leader vectors, the result of the division of the co-ordinate Xi raised to the power p by a delta precision factor, the result of the division being rounded to the nearest whole number. The method does not comprise a step of determining leader vectors.

Abstract: The invention concerns a method of converting raw multidimensional digital data corresponding to points making up a 2D or 3D image of unknown size and an associated system. The method comprises: the sizing a multidimensional window for traversing of said image, the said sizing depending on the size of a buffer; the traversing the said image comprising the movement of the said window in the image along the axes of the image; at each position of the said window in the image: the step of acquisition and loading, in the said buffer, of the data of the part of the image defined by the window; the conversion by calculation of the multidimensional wavelet transform of the said loaded part by means of at least one compact support filter for generating low- and high-frequency coefficients; the saving of the said coefficients generated. Application to wavelet transformation synchronously with the acquisition of medical or seismic images.

Abstract: An encoding device and method are provided for encoding at least one image split into partitions. The method implements, for a current partition to be encoded, steps of: selecting at least one causal partition already encoded and then decoded; calculating at least one optimal encoding parameter associated with the selected causal partition, according to a predetermined criterion of encoding performance, by comparing a plurality of encoding parameters applied to the selected causal partition; and encoding the current partition by using the calculated optimum encoding parameter.

Abstract: The disclosure relates to a method for treating digital data, including a quantification step of calculating, in a space of dimension d, at least one vector index I1 for at least some of the vectors 1, the vectors 1 forming input data descriptors. The method is characterised in that the vector index I1 corresponds to the number of vectors preceding the vector 1 in the reverse lexicographic order, without involving a step of determining all of the vectors.
