Quasi Lossless Satellite Image Compression

IGARSS 2022 - 2022 IEEE International Geoscience and Remote Sensing Symposium, 2022
We describe an end-to-end trainable neural network for satellite image compression. The proposed approach builds upon an image compression scheme based on variational autoencoders with a learned hyper-prior that captures dependencies in the latent space for entropy coding.
