Title:
METHOD AND APPARATUS FOR VIDEO CODING USING PALETTE MODE BASED ON PROXIMITY INFORMATION
Document Type and Number:
WIPO Patent Application WO/2023/182697
Kind Code:
A1
Abstract:
A method and a device for video coding using a palette mode based on proximity information are disclosed. In the present embodiment, an image decoding device generates a palette table for the current block, derives an index map by using proximity information about the current block, and restores samples of the current block on the basis of the index map and the palette table. Here, the proximity information about the current block includes a template in an adjacent block vector of the current block or in an adjacent pre-restored region of the current block, the index map includes an index for each sample of the current block, and the index for each sample indicates an entry of the palette table having a color value corresponding to the sample of the current block.
