Abstract
A hybrid palette-DPCM coding implementation generates a palette for the most dominant colors in an image block and an index block based on the palette. Additionally, for pixels that are not in the palette, DPCM coding is utilized. By combining palette coding and DPCM coding, the image encoding process is optimized.
