Abstract

Method and apparatus for encoding and decoding an input signal, for example an image, a video or a 3D object, using a hybrid Implicit Neural Representation network are provided. The method comprises obtaining one or more syntax elements providing for reconstructing at least one part of the input signal using at least one hybrid Implicit Neural Representation network, the at least one hybrid Implicit Neural Representation network comprising: at least one mapping transformation that maps input coordinates of the image or 3D object to at least one grid of features, and an INR network that takes as input, features of the at least one grid of features and outputs values of the image or 3D object at the input coordinates, wherein the one or more syntax elements comprises a first syntax element indicating whether a first grid of features of the at least one grid of features has same dimensions as dimensions of the input coordinates, and signaling the one or more syntax elements in a bitstream.
