Abstract:
A method is provided for coding at least one image split up into partitions, a current partition to be coded containing data, at least one data item of which is allotted a sign. The coding method includes, for the current partition, the following steps: calculating the value of a function representative of the data of the current partition with the exclusion of the sign; comparing the calculated value with a predetermined value of the sign; as a function of the result of the comparison, modifying or not modifying at least one of the data items of the current partition, in the case of modification, coding the at least one modified data item.

Claim (Index 2):
A method for decoding a sign-data-hiding enabled data signal representative of at least one image split up into partitions which has been previously coded, the decoding method comprising:\n receiving a set of coefficients representing a partition of the image; identifying a first non-zero coefficient within the set of coefficients; identifying a last non-zero coefficient within the set of coefficients; determining a set of modifiable coefficients in the set of coefficients wherein the modifiable coefficients include the first non-zero coefficient, the last non-zero coefficient and all the coefficients between the first and the last non-zero coefficient; determining that a sign for the first non-zero coefficient is hidden if a count of the modifiable coefficients if greater than a threshold; and in response to determining that the sign for the first non-zero coefficient is hidden:\n (i) calculating a sum of amplitude information of the modifiable coefficients; \n (ii) calculating, using the sum of the amplitude information of the modifiable coefficients, parity data; and \n (iii) designating, on the basis of the parity data, a sign for the first non-zero coefficient; and \n dequantizing the set of coefficients representing the partition of the image.
