Method and Device for Encoding a Sequence of Images and Method and Device for Decoding a Sequence of Image

摘要

A method and device for deriving motion information of an image portion of an image predicted by motion prediction with respect to at least one reference image, the method comprising for said image portion: obtaining a number i of motion information predictors 808 of a second set of motion information predictors 814 taken from a first set of motion information predictors for decoding the image portion; generating said second set of motion information predictors 814 consisting of said number i of motion information predictors, wherein there are no duplicates among the i motion information predictors of said second set. A method and device for of decoding a bitstream, and a method and device for encoding a sequence of image including a method for deriving motion information of an image portion of an image predicted by motion prediction with respect to at least one reference image as described above.

1. A method of decoding a bitstream comprising an encoded sequence of images, at least one portion of an image having been encoded by motion compensation with respect to a reference image portion, the method comprising for at least one image portion to be decoded:
obtaining an index i of a selected motion information predictor of a first set of motion information predictors for decoding the image portion; generating a second set of motion information predictors consisting of said index number i of motion information predictors wherein there are no duplicates among the i motion information predictors of said second set; and retrieving, for decoding of the image portion, the motion information predictor indexed by index i from the second set of motion information predictors.
