Lossy Image Compression with Foundation Diffusion Models

no code implementations12 Apr 2024 Lucas Relic, Roberto Azevedo, Markus Gross, Christopher Schroers

Incorporating diffusion models in the image compression domain has the potential to produce realistic and detailed reconstructions, especially at extremely low bitrates.

Video Compression With Entropy-Constrained Neural Representations

no code implementations CVPR 2023 Carlos Gomes, Roberto Azevedo, Christopher Schroers

This performance gap can be explained by the fact that current NVR methods: i) use architectures that do not efficiently obtain a compact representation of temporal and spatial information; and ii) minimize rate and distortion disjointly (first overfitting a network on a video and then using heuristic techniques such as post-training quantization or weight pruning to compress the model).

Bridging the Gap between Semantics and Multimedia Processing

no code implementations25 Nov 2019 Marcio Ferreira Moreno, Guilherme Lima, Rodrigo Costa Mesquita Santos, Roberto Azevedo, Markus Endler

In this paper, we give an overview of the semantic gap problem in multimedia and discuss how machine learning and symbolic AI can be combined to narrow this gap.
