Title:
COMPOUND MOTION-COMPENSATED PREDICTION
Document Type and Number:
Japanese Patent JP2022069546
Kind Code:
A
Abstract:
To provide compound motion-compensated prediction methods and devices.SOLUTION: A prediction scheme is selected for encoding or decoding a video block. A first compound motion block can be determined by weighting distances from a first reference frame to a video frame and from a second reference frame to the video frame using one or more quantized weighting coefficients. A second compound motion block can be determined based on an average of pixel values from a video block of the first reference frame and pixel values from a video block of the second reference frame. One of the first compound motion block and the second compound motion block is selected and used to generate a prediction block. Alternatively, data encoded into a bitstream including the video frame can be used to determine which compound motion block is used to generate the prediction block. The current block of the video frame is then encoded or decoded using the prediction block.SELECTED DRAWING: Figure 7
