  1. 6. Detection of Human Emotion from Noise Speech

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Sai Chandra Sekhar Reddy Nallamilli; Nihanth Kandi; [2020]
    Nyckelord :Neural Network; Activation Function; Fast Fourier Transform; Karhunen-Loeve Transform; speech enhancement; filtering; Wavelet Transform; Speech preprocessing; signal to noise ratio; shallow neural network;

    Sammanfattning : Detection of a human emotion from human speech is always a challenging task. Factors like intonation, pitch, and loudness of signal vary from different human voice. So, it's important to know the exact pitch, intonation and loudness of a speech for making it a challenging task for detection. LÄS MER

  3. 7. Vision based facial emotion detection using deep convolutional neural networks

    Kandidat-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Fredrik Julin; [2019]
    Nyckelord :Computer vision; Deep learning; Convolutional neural network; CNN; Neural network; Machine learning; emotion detection; facial expression recognition; real-time; face detection;

    Sammanfattning : Emotion detection, also known as Facial expression recognition, is the art of mapping an emotion to some sort of input data taken from a human. This is a powerful tool to extract valuable information from individuals which can be used as data for many different purposes, ranging from medical conditions such as depression to customer feedback.

  4. 8. Are people with higher interoceptive sensitivity really morealtruistic? : A replication study

    Kandidat-uppsats, Stockholms universitet/Psykologiska institutionen

    Författare :Gustaf Nilsson; [2018]
    Nyckelord :emotion interoception altruism monetary generosity interoceptive sensitivity replication;

    Sammanfattning : Interoceptive sensitivity (IS) is the ability to feel one’s own bodilysignals accurately. The connection between IS, emotional processingand consecutive behavior is a popular research topic. In this study, Itried to replicate a study by Piech and colleagues from 2017. LÄS MER

  5. 9. Facial emotion detection using deep learning

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Daniel Llatas Spiers; [2016]
    Nyckelord :;

    Sammanfattning : The use of machines to perform different tasks is constantly increasing in society. Providing machines with perception can lead them to perform a great variety of tasks; even very complex ones such as elderly care. Machine perception requires that machines understand about their environment and interlocutor's intention. LÄS MER

  7. 10. Micro-Expression Extraction For Lie Detection Using Eulerian Video (Motion and Color) Magnication

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling
