Abstract: A method of processing a video sequence is proposed, which comprises, for a video encoding tool of a set of video encoding tools configured for encoding the video sequence comprised in a video encoder, determining an efficiency value based on an encoding performance value and an encoding computational complexity value of the video encoding tool for encoding the video sequence, and determining, based on the efficiency value of the video encoding tool, whether to configure the video encoder to use the video encoding tool for the encoding of the video sequence.

Abstract: A method for processing a current image of a set of images is proposed, which comprises, at a video processing device comprising a processor: determining a target pixel area in the current image; obtaining a hidden image, comprising a source pixel area, of the set of images; dividing the current image into blocks for an encoding of the blocks according to an encoding sequence; and for a block of the target pixel area: determining a motion vector pointing to a block of the source pixel area in the hidden image corresponding to the block of the target pixel area, and based on the motion vector, encoding the block of the target pixel area according to a temporal correlation prediction mode pursuant to which no pixel residual representing a difference between the block of the target pixel area and the corresponding block of the source pixel area is generated.

Abstract: A method of processing a first image in a first plurality of images, wherein the first image is divided into a plurality of pixel blocks, is proposed, which comprises, for a current block of the first image: selecting, in a set of a plurality of predefined interpolation filters, an interpolation filter based on a prediction of an interpolation filter determined by a supervised learning algorithm to which data related to the current block is input; and using the selected interpolation filter for calculating fractional pixel values in a second image of the plurality of images for a temporal prediction of pixels of the current block based on a reference block correlated to the current block in the second image, wherein the second image is distinct from the first image and was previously encoded according to an image encoding sequence for encoding the images of the plurality of images.
