1. A computer-implemented method for lossy image or video compression, transmission and decoding, the method including the steps of:
(i) receiving an input image at a first computer system;
(ii) encoding the input image using an invertible neural network (INN), using the first computer system, to produce a latent representation;
(iii) quantizing the latent representation using the first computer system to produce a quantized latent;
(iv) entropy encoding the quantized latent into a bitstream, using the first computer system;
(v) transmitting the bitstream to a second computer system;
(vi) the second computer system entropy decoding the bitstream to produce the quantized latent; and
(vii) the second computer system using an inverse of the INN to produce an output image from the quantized latent, wherein the output image is an approximation of the input image.
