Abstract
Aspects of the disclosure includes methods and apparatuses for mesh coding. The method includes receiving coded information of a bitstream of a mesh that includes a plurality of residuals. The method includes performing entropy decoding on a current residual in the plurality of residuals based on a maximum value for arithmetic coding and a type of entropy coding for a sign of the current residual in the plurality of residuals, and reconstructing the mesh based on the entropy decoded current residual. The sign of the current residual is determined based on a previous sign and whether the sign of the current residual is flipped from the previous sign, or the maximum value for the arithmetic coding is based on a bit depth associated with the current residual.
