Abstract
The invention concerns a method for decoding a video sequence encoded according to a predictive format, which video sequence includes predicted images containing encoded residual data representing differences between the respective predicted image and a respective reference image in the video sequence. The method comprises, for a current predicted image of the video sequence, the steps of: determining (E51) at least one first area of the current predicted image according to meeting of a predetermined criterion; for at least part of the determined at least one first area, applying an error concealment method (E514), said error concealment method using residual data of the current predicted image relative to said part.
Claims18
A method for decoding a video sequence encoded according to a predictive format, which video sequence includes predicted images containing encoded residual data representing differences between the respective predicted image and a respective reference image in the video sequence, the method comprising, for a current predicted image of the video sequence:
- determining at least one first area of the current predicted image according to meeting of a predetermined criterion;
- for at least part of the determined at least one first area, applying an error concealment method, said error concealment method using residual data of the current predicted image relative to said part.
A device for decoding a video sequence encoded according to a predictive format, which video sequence includes predicted images containing encoded residual data representing differences between the respective predicted image and a respective reference image in the video sequence, the device comprising:
- means for determining at least one first area of a current predicted image according to meeting of a predetermined criterion;
- means for applying an error concealment method to at least part of the determined at least one first area, said error concealment method using residual data of the current predicted image relative to said part.
A non-transitory computer-readable carrier medium storing a program which, when executed by a computer or a processor in a device for decoding a video sequence, causes the device to carry out a method for decoding a video sequence encoded according to a predictive format, which video sequence includes predicted images containing encoded residual data representing differences between the respective predicted image and a respective reference image in the video sequence, the method comprising, for a current predicted image of the video sequence:
- determining at least one first area of the current predicted image according to meeting of a predetermined criterion;
- for at least part of the determined at least one first area, applying an error concealment method, said error concealment method using residual data of the current predicted image relative to said part.
(canceled)
A device for decoding a video sequence encoded according to a predictive format, which video sequence includes predicted images containing encoded residual data representing differences between the respective predicted image and a respective reference image in the video sequence, the device comprising:
- a determiner that determines at least one first area of a current predicted image according to meeting of a predetermined criterion;
- and
- a processor that applies an error concealment method to at least part of the determined at least one first area, said error concealment method using residual data of the current predicted image relative to said part.
