Original Abstract Submitted
This disclosure provides a method and apparatus for compressing 3-dimensional volume data. The method for encoding a TSDF volume may comprise: lossily encoding magnitude information of a Truncated Signed Distance Field (TSDF) volume based on a hyperprior model; and losslessly encoding sign information of the TSDF volume based on the hyperprior model, wherein the lossy encoding comprises selecting and entropy-encoding some elements from a latent vector for the TSDF volume based on selection information obtained through the hyperprior model.
