Latest Patents

Wu's most recent patents include two groundbreaking inventions in the realm of palette mode video encoding.

Firstly, the **Residual-free Palette Mode Coding** patent introduces an encoder that implements a residual-free palette encoding mode. This method uses a block of pixels to derive a palette table with fewer palette colors than the pixel colors in that block. By omitting the calculations of residuals representing errors during encoding, the technology enables the creation of less complex encoder hardware while sacrificing only a slight degree of color accuracy. Moreover, when multiple encoding modes are available, the encoder can opt for the residual-free palette encoding mode if it determines that this option presents the lowest cost among the available alternatives.

Secondly, the **Palette Mode Video Encoding Utilizing Hierarchical Palette Table Generation** patent describes an encoder that encodes an image portion by recursively partitioning it into a hierarchy of levels. The top level consists of a single block representing the entire portion, with subsequent levels divided into smaller blocks. For each bottom-level block, a palette table is generated based on its pixels. The encoder then generates palette tables for higher-level blocks by selecting palette colors from those of the lower blocks. This hierarchical approach facilitates creating a color index map, which is used to encode the representation of the image portion effectively.
