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 ...

Description Lower limb prostheses support individuals with lower limb amputations in daily tasks, including walking, stairs climbing or running. For adaptation to the current gait situation, it is beneficial to sense the surrounding environment, e.g., with visual sensors. The obtained situation awa...

Description 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...

Proposal for a Master Thesis Topic: Deep Learning Methods for Bearing Fault Detection   Description: The measurable vibrations of machines during operation contain much information about the machine's condition. During normal operation a machine exhibits a characteristic vibration signat...

Proposal for a Master Thesis Topic: 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...

Proposal for a Master Thesis Topic: Acoustic Scene Analysis with Manifold Learning Description: The knowledge of physical parameters describing the acoustics of a room is highly relevant for a multitude of applications, e.g., automatic speech recognition. The reverberation time T60 is one of the...

Proposal for a Master Thesis Topic: Acoustic Source Tracking using Manifold Learning Description: The aim of acoustic source localization is to estimate the position of one or several sound sources from observed microphone signals. For moving sources usually a tracking algorithm is appended, whi...

Proposal for a Master Thesis Topic: Adaptive Speech Dereverberation based on Linear Prediction Description: A speech signal recorded in a room will inevitably be affected by reverberant components produced by the reflections of sound waves on walls or objects in the acoustic environment. Reverbe...

Proposal for a Master Thesis Topic: Analyse und Steuerung von Adaptiven Mikrofonarrays Description: Robot audition describes the research area that aims at providing humanoid robots with ’technical ears’ to allow, e.g., reaction to acoustic events and speech communication with humans. For this, ...

Proposal for a Master Thesis Topic: Blind Blind Sampling Rate Offset Estimation for Wireless Acoustic Sensor Networks through Coherence Drift Estimation Description: In Wireless Acoustic Sensor Networks (WASNs) spatially distributed nodes allow for multi-channel array signal processing tasks, e....

Proposal for a Master Thesis Topic: Coherence-based Multichannel Double-talk Detection Description: In a multichannel acoustic echo cancellation scenario, an active near-end speaker poses a serious challenge to the identification of the acoustic echo paths between loudspeaker and microphones, as...

Proposal for a Master Thesis 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...

Proposal for a Master Thesis Topic: Dereverberation with the Weighted Prediction Error Method Description: A speech signal recorded in a room will inevitably be affected by reverberant components produced by the reflections of sound waves on walls or objects in the acoustic environment. Reverber...

Proposal for a Master Thesis Topic: Evaluation of the Spatial Distribution of Ego-Noise employing Multichannel Non-Negative Matrix Factorization Description: Mobile robots generate significant self-induced noise, e.g., by its mechanical joints and motors, which is referred to as ego-noise. Its s...

Proposal for a Master Thesis Topic: Learning Data-Dependent Transformations for Ego-Noise Suppression Description: Robot audition describes the research area of human-robot interaction by speech. Therefore, robots are often equipped with microphone arrays to capture their surrounding acoustic s...

Proposal for a Master Thesis Topic: Source Localization using Manifold Learning Description: Acoustic source localization is a precondition for many subsequent signal processing algorithms. It can be accomplished by mapping one or more acoustic features via an analytical mathematical model or ...
