Abstract: Methods and circuitry are provided for finding an optimum vector for motion-compensated prediction in video coding. Processing circuitry is operable to define a block in an image, the defined block having a plurality of pixels. A first set of residuals is calculated using a first motion vector. Each residual of the first set of residuals corresponds to a respective pixel within the plurality of pixels. Additionally, a first plurality of absolute differences is calculated. Each absolute difference in the first plurality of absolute differences is between a pair of residuals in the first set of residuals. The first plurality of absolute differences is summed, and is compared to sums of absolute differences of residuals calculated using other motion vectors. The motion vector corresponding to the lowest sum may be identified as an optimum motion vector.

Abstract: Techniques are described for palette-based coding. In palette-based coding, a video coder may form a palette as a table of colors for representing video data of a given block. Palette-based coding may be useful for coding blocks of video data having a relatively small number of colors. Rather than coding actual pixel values or their residuals for the given block, the video coder may code index values for one or more of the pixels. The index values map the pixels to entries in the palette representing the colors of the pixels. Techniques are described for determining whether to disable filtering, such as deblocking filtering or sample adaptive offset (SAO) filtering, of palette coded blocks at a video encoder or a video decoder. Techniques are also described for modify a palette size and palette entries of a palette at the video encoder based on rate-distortion costs.
