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.
