Perceptually-Weighted Video Quality Metric for Asymmetric Encoded Sports Videos
Anna Meyer, Jonas Janzen, Diwakara Reddy +5
Objective video quality metrics commonly assume uniform spatial attention, an assumption that conflicts with the selective nature of human visual perception, particularly in sports…
LRC-DHVC: Towards Local Rate Control in Neural Video Compression
Marc Windsheimer, Simon Deniffel, André Kaup
Local rate control is a key enabler to generalize image and video compression for dedicated challenges, such as video coding for machines. While traditional hybrid video coding can…
On Annotation-free Optimization of Video Coding for Machines
Marc Windsheimer, Fabian Brand, André Kaup
Today, image and video data is not only viewed by humans, but also automatically analyzed by computer vision algorithms. However, current coding standards are optimized for human p…
Multiscale Augmented Normalizing Flows for Image Compression
Marc Windsheimer, Fabian Brand, André Kaup
Most learning-based image compression methods lack efficiency for high image quality due to their non-invertible design. The decoding function of the frequently applied compressive…
