摘要： A video coding for machines (VCM) encoder for combined lossless and lossy encoding includes a feature encoder, the feature encoder configured to encode a sub-picture containing a feature in an input video and provide an indication of the sub-picture, and a video encoder, the video encoder configured to receive an indication of the sub-picture from the feature encoder and encode the sub-picture using a lossy encoding protocol.

摘要： An encoder for video encoding and decoding with long term reference picture retention. The encoder generates an encoded bitstream for a compliant decoder. At the decoder, coded pictures are decoded using a list of references pictures, of which at least one is a long term reference picture. A first picture is decoded using the long term reference picture. A second picture is decoded without using the long term reference picture which is inactive but is retained in a buffer. A subsequent picture is then decoded again using the long term reference picture.

摘要： A decoder is configured to receive a bit stream including a current frame and a picture header associated with the entire current frame, determine, as a function of the picture header, that one global motion mode is enabled for the entire current frame, the enabled global motion mode being selected from a group including translational motion, 4-parameter affine motion, and 6-parameter affine motion, detect, based on the enabled global motion mode, a plurality of parameters applicable to the entire frame, and decode the current frame using the detected parameters.

摘要： A method is provided for processing a video bitstream which includes a first picture and a sequence parameter set containing information indicating a mode is enabled in which a first area of a picture can be extracted and replaced by a second area of another picture. Using the mode, the first picture is modified by extracting the first area and replacing the extracted area with the second area from the other picture. The modified first picture is stored and a predictor is formed using the modified first picture as a reference picture. A block of a subsequent picture is decoded using the predictor.

摘要： A method includes receiving a bit stream; determining, using the bit stream and for a current frame, whether the current frame is available to be used as a reference frame; setting, in response to determining that the current frame is available to be used as a reference frame, a variable characterizing that an adaptive resolution management mode is disallowed; and reconstructing pixel data of the current frame, wherein the adaptive resolution management mode is disallowed. Related apparatus, systems, techniques and articles are also described.

摘要： A video decoder is configured to receive a bitstream including a first coded picture having a first resolution and a second coded picture having a second resolution, wherein the first coded picture is an intra-coded picture, parameters defining a cropping window. The decoder decodes the first coded picture and stores the first picture as a reference picture, determines a scaling factor from at least one parameter in the bitstream defining the first cropping window, determines a predictor for the second picture from the reference picture and the scaling factor, decodes the second coded picture using the predictor, and outputs for display the first picture as cropped in accordance with the parameters defining the cropping window.
