    Surface tracking assessment and interaction in texture space by Johannes Furch, Anna Hilsmann, Peter Eisert

    Published 2017-06-01
    “…Abstract In this paper, we present a novel approach for assessing and interacting with surface tracking algorithms targeting video manipulation in post-production. As tracking inaccuracies are unavoidable, we enable the user to provide small hints to the algorithms instead of correcting erroneous results afterwards. …”

    Image and video generation via deep learning by Jiang, Liming

    Published 2023
    “…The first attempt is to construct a large-scale facial video dataset, DeeperForensics-1.0, to facilitate the following research and prevent the negative impact of generated data via better video manipulation. After securing the countermeasures, a versatile Two-Stream Image-to-image Translation (TSIT) framework is proposed, which has high practical value. …”

    Focusing on Future Consequences Enhances Self-Controlled Dietary Choices by Johanna Kruse, Franziska M. Korb, Caroline Surrey, Uta Wolfensteller, Thomas Goschke, Stefan Scherbaum

    Published 2023-12-01
    “…Instruction to focus on long-term consequences compared to short-term consequences increased the number of healthy choices, reduced response times for healthy decisions, and increased the influence of health aspects during the decision-making process. The effect of video manipulation showed greater variability. While focusing on long-term consequences facilitated healthy food choices and reduced the underlying decision conflict, the current mindset appeared to have a minor influence.…”

    Information Accrual From the Period Preceding Racket-Ball Contact for Tennis Ground Strokes: Inferences From Stochastic Masking by Sepehr Jalali, Sian E. Martin, Tandra Ghose, Richard M. Buscombe, Joshua A. Solomon, Kielan Yarrow

    Published 2019-08-01
    “…This result is broadly consistent with prior work using nonstochastic approaches to video manipulation, and cannot be an artifact of temporal smear from information accrued after racket-ball contact, because no such information was present.…”

    Real Life Scenes to Study Emotions in Women by Ana Carolina Aguiar-Moreira, Thiago Maehara Pereira Pinho, Gabriela Campos Oliveira Filgueira, Rosa Wanda Diez-Garcia

    Published 2017-04-01
    “…The methodology adopted herein combined qualitative and quantitative methods and involved three distinct study stages: (i) use of a descriptive question to identify daily situations that evoked negative emotions among women; (ii) construction of everyday life scenes; (iii) assessment of how effectively the constructed videos manipulated emotions. The visual analog scale (VAS), a descriptive question, and a focus group were used to discuss the negative emotion and neutral emotional condition evoked during the experiment. …”
