Description
Common image compression techniques tolerate errors in the reconstructed image to allow high compression. These errors can not only reduce visual quality but also affect the performance of classification and detection systems.
One possible application is the classification of emotions ...

This thesis can be written in German and in English.
The need to transmit screen content data is more important than ever. Online conferencing, screen sharing and remote desktop are just a few applications where screen content data has to be compressed. However, conventional image an...
Point Clouds are becoming one of the most common data structures to represent 3D scenes as it enables six degrees of freedom (6DoF) viewing experience. Point Cloud Data has been used in many applications, from immersive media, and autonomous driving to healthcare.
However, a typical...

A probabilistic approach to image resampling
Description:
Image processing often produces pixels that are not located on integer pixel positions. If an image is e.g. rotated, the pixels are located on non-integer positions after the rotation. We refer to these...

Topic:
Double-Talk Detection for Robot Audition
Description:
In an Acoustic Echo Cancellation (AEC) problem, the performance of an acoustic echo canceler is usually impaired by the presence of a near-end interferer. This double-talk situation is often addressed using...
