The present disclosure relates to a motion compensation method and module, a chip, an electronic device, and a storage medium, to improve the problem of haloes easily appearing on the edges of moving objects.

A method, computing device and a computer-readable storage medium for encoding and decoding video data for streaming are provided. The method includes receiving video data comprising frames; accessing a dataset comprising at least one image expected to have similarity to at least one of the frames of the received video data; selecting an image or a portion of the image, from the dataset based on similarity to at least a portion of a first frame of the received video data; generating a frame using the image or the portion of the image selected from the dataset; encoding the generated frame and the frames of the received video data to produce encoded video data; and removing data corresponding to the generated frame from the encoded video data to produce modified encoded video data and generating data identifying the image or the portion of the image selected from the dataset.

A method for encoding a picture of a video sequence in a bit stream that reduces slice header parsing overhead is provided. The method includes determining weighting factors that may be used for weighted prediction in encoding at least one slice of the picture, wherein a total number of the weighting factors is constrained to not exceed a predetermined threshold number of weighting factors, wherein the threshold number is less than a maximum possible number of weighting factors, and signaling weighted prediction parameters including the weighting factors in a slice header in the bit stream.

Computer processor hardware receives a first set of adjustment values. The first set of adjustment values specify adjustments to be made to a predicted rendition of a signal generated at a first level of quality to reconstruct a rendition of the signal at the first level of quality. The computer processor hardware processes the first set of adjustment values and derives a second set of adjustment values based on the first set of adjustment values and a rendition of the signal at a second level of quality. The second level of quality is lower than the first level of quality.

There is provided an encoding device, an encoding method, a decoding device, and a decoding method capable of generating a more accurate three-dimensional model. A three-dimensional model generating unit generates three-dimensional model information representing a three-dimensional model of a subject on the basis of a plurality of captured images and active depth information, and a conversion processing unit converts the three-dimensional model represented by the three-dimensional model information into a plurality of two-dimensional images by projecting the three-dimensional model from a plurality of directions, and generates depth information representing a depth from an arbitrary viewpoint to the three-dimensional model by using the plurality of two-dimensional images. Then, transmit data including the plurality of two-dimensional images, the depth information, and the active depth information is transmitted to the decoding device. The present technology can be applied to, for example, a free viewpoint video transmission system.

A vehicle is provided and includes an image acquisition device and an image processing apparatus that receives an original frame for an image obtained by the image acquisition device at a set time interval in the parking state and obtains a key frame having the same pixel with each other by comparing a plurality of original frames received at the set time interval. The image processing apparatus obtains a plurality of delta frames having pixels different from the reference original frame from remaining original frames by comparing each of the reference original frame and the remaining original frames among the plurality of frames and compresses the key frame and the plurality of delta frames, respectively. A storage device stores the key frame and a plurality of delta frames compressed by the image processing apparatus.
