  1. 1. Despeckling Echocardiograms Using Generative Adversarial Networks

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Falk DIppel; [2023-10-23]
    Keywords : Generative adversarial network; deep learning; echocardiography; speckle noise; denoising; segmentation;

    Abstract : Previous research had shown that generative adversarial networks (GANs) are capable of despeckling echocardiograms (echos) through image-to-image translation in real-time once trained. However, only limited information regarding the quality of denoised echos and explainability of useful GAN components is provided. READ MORE

  3. 2. Speech Enhancement in Hands-Free Device (Hearing Aid) with emphasis on Elko's Beamformer

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : TELAGAREDDI S N U V RAMESH; [2012]
    Keywords : Speech Enhancement; Speech intelligibility; Speech Communication and Beamforming ;

    Abstract : In general, an uncontrolled environment may contain degradation components like background noise, speech from other speakers etc. along with required speech components. It is very tough to concentrate only on speech signals in presence of background noise for normal listeners and hearing impaired persons. READ MORE

  4. 3. Attention to the periphery attenuates the EPN and LPP

    University essay from Psykologiska institutionen

    Author : Elmeri Syrjänen; [2011]
    Keywords : Attention; Emotion; Motivation; ERP; EPN; LPP;

    Abstract : Current research shows that emotions have an important role in guiding attention and cognitions especially when the emotional stimuli are affective. Load theory proposes that when the perceptual load on attention is sufficiently high, irrelevant emotional stimuli is no longer attended to and thus will not produce a distracting effect. READ MORE

  5. 4. Combining Acoustic Echo Cancellation and Suppression

    University essay from Institutionen för systemteknik

    Author : Fredrik Wallin; [2003]
    Keywords : Reglerteknik; acoustic echo cancellation; acoustic echo suppression; hybrid system; subjective listening tests; PESQ; perception; Reglerteknik;

    Abstract : The acoustic echo problem arises whenever there is acoustic coupling between a loudspeaker and a microphone, such as in a teleconference system. This problem is traditionally solved by using an acoustic echo canceler (AEC), which models the echo path with adaptive filters. READ MORE
