Learned Wavelet Video Coding using Motion Compensated Temporal Filtering

no code implementations25 May 2023 Anna Meyer, Fabian Brand, André Kaup

In our experiments, we compare our MCTF-based approach to learning-based conditional coders and traditional hybrid video coding.

Video Compression

The Bjøntegaard Bible -- Why your Way of Comparing Video Codecs May Be Wrong

1 code implementation25 Apr 2023 Christian Herglotz, Hannah Och, Anna Meyer, Geetha Ramasubbu, Lena Eichermüller, Matthias Kränzler, Fabian Brand, Kristian Fischer, Dat Thanh Nguyen, Andy Regensky, André Kaup

Using additional supporting points inbetween standard points defined by parameters such as the quantization parameter, we assess the interpolation error of the Bj{\o}ntegaard-Delta (BD) calculus and its impact on the final BD value.

Multispectral Image Compression Based on HEVC Using Pel-Recursive Inter-Band Prediction

no code implementations9 Mar 2023 Anna Meyer, Nils Genser, André Kaup

In this paper, we propose a cross-spectral compression scheme for efficiently coding multispectral data based on HEVC.

Image Compression

A novel Cross-Component Context Model for End-to-End Wavelet Image Coding

no code implementations9 Mar 2023 Anna Meyer, André Kaup

In this paper, we explore a promising alternative approach for neural compression, with an autoencoder whose latent space represents a nonlinear wavelet decomposition.

A machine learning based algorithm selection method to solve the minimum cost flow problem

1 code implementation3 Oct 2022 Philipp Herrmann, Anna Meyer, Stefan Ruzika, Luca E. Schäfer, Fabian von der Warth

The minimum cost flow problem is one of the most studied network optimization problems and appears in numerous applications.
