Abstract: According to examples, a learning based, end-to-end compression system may include an encoder, which may receive a complex hologram image and encode a latent code for a real component and an imaginary component of the hologram image. The system may also include a quantizer to quantize the latent code and a transform block, which may entropy-code the quantized latent code to obtain a compressed image. The system may further include a generator to decode the compressed image and a discriminator, which may classify the decoded image to obtain an uncompressed image. In case of holographic video input, the encoder may encode a frame to obtain a standard compressed frame and a residual to a latent code. The generator may decode the standard compressed frame and the latent code to obtain a reconstructed residual, and the discriminator may combine the uncompressed standard frame and the reconstructed residual.
