MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202647123259 A) filed by Qualcomm Incorporated on October 14, 2026, for V-Dmc Displacement Lifting Transform Offset.
Inventors include Hooda, Reetu; Van Der Auwera, Geert; Akhtar, Anique; Ramasubramonian, Adarsh Krishnan; and Karczewicz, Marta.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: Certain aspects of the disclosure provide for encoding and decoding mesh data using a lifting transform. Transform coefficients are determined by applying a lifting transform on displacement vectors representing mesh data. To address systematic bias, such as a non-zero mean distribution, an offset can be determined and applied to transform coefficients per level of detail. An encoder quantizes transform coefficients adjusted by the offset and signals the quantized coefficients and the offset in a bitstream of encoded mesh data. A decoder extracts the quantized transform coefficients and offset per level of detail from the bitstream, inverse quantizes the transform coefficients, applies the offset, and inverse transforms the result to recover displacement vectors and reconstruct the mesh data.
