Abstract:
A method for encoding an image having been cut up into partitions. The method includes: predicting data of a current partition based on an already encoded and then decoded reference partition, generating a predicted partition; determining residual data by comparing data relating to the current partition with the predicted partition, the residual data associated with various digital data items. Prior producing a signal containing the encoded information, performing the following steps: determining, from the predetermined residual data, a subset containing residual data capable of being modified; calculating the value of a function representative of the residual data; comparing the calculated value with a value of at least one of the digital data items; based on the comparison, modification or non-modification of at least one of the residual data items of the subset; and, in the event of a modification, entropy encoding the at least one modified residual data item.

Claim (Index 2):
A method for decoding a sign-data-hiding enabled partition of an image, the method comprising:\n receiving a set of context-based adaptive binary arithmetic coding (CABAC) encoded coefficients from an encoder; decoding the set of CABAC encoded coefficients to generate a set of coefficients representing a residual block for the sign-data-hiding enabled partition, the set of coefficients including a first non-zero coefficient that is without a sign designation; applying a function to the set of coefficients to generate sign data, wherein applying the function to the set of coefficients comprises: computing a sum of modifiable coefficients in the set of coefficients, wherein the modifiable coefficients include a first non-zero coefficient according to a reverse scan order of the residual block, a last non-zero coefficient according to the reverse scan order of the residual block, and coefficients between the first and the last non-zero coefficients; and computing remainder data based on a division between the sum and a specific number; designating a sign for the first non-zero coefficient based on the sign data, wherein designating the sign for the first non-zero coefficient comprises:\n designating the sign for the first non-zero coefficient based on the remainder data; \n dequantizing the set of coefficients including the first non-zero coefficient with the designated sign to generate a dequantized block of coefficients; and \n inverse transforming the dequantized block of coefficients to generate a residual block.
