Quantized Decoder in Learned Image Compression for Deterministic Reconstruction

no code implementations18 Dec 2023 Esin Koyuncu, Timofey Solovyev, Johannes Sauer, Elena Alshina, André Kaup

Learned image compression has a problem of non-bit-exact reconstruction due to different calculations of floating point arithmetic on different devices.

Image Compression Quantization

Device Interoperability for Learned Image Compression with Weights and Activations Quantization

no code implementations2 Dec 2022 Esin Koyuncu, Timofey Solovyev, Elena Alshina, André Kaup

Learning-based image compression has improved to a level where it can outperform traditional image codecs such as HEVC and VVC in terms of coding performance.
