DETERMINING APPLICATION OF DEBLOCKING FILTERING TO PALETTE CODED BLOCKS IN VIDEO CODING

摘要

Techniques are described for palette-based video coding. In palette-based coding, a video coder may form a so-called "palette" as a table of colors for representing video data of a given block of video data. 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 the application of deblocking filtering for pixels of palette coded blocks at a video encoder or a video decoder. In addition, techniques are described for determining quantization parameter (QP) values and delta QP values used to quantize escape pixel values of palette coded blocks at the video encoder or the video decoder.
