    Sammanfattning : Idag är det vanligt att det sker filmning av evenemang utan att man använder sig av en professionell videofotograf. Det kan vara knatteligans fotbollsmatch, konferensmöten, undervisning eller YouTube-klipp. För att slippa ha en kameraman kan man använda sig av något som kallas för objektföljningskameror. LÄS MER

  3. 2. Object Detection with Deep Convolutional Neural Networks in Images with Various Lighting Conditions and Limited Resolution

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Roman Landin; [2021]
    Nyckelord :Object detection; Super Resolution image generation; Low-Light image enhancement; Computer Vision; Detektion av objekt; Bildgenerering med superupplösning; Förbättring av bilder med dålig belysning; Datorseende;

    Sammanfattning : Computer vision is a key component of any autonomous system. Real world computer vision applications rely on a proper and accurate detection and classification of objects. A detection algorithm that doesn’t guarantee reasonable detection accuracy is not applicable in real time scenarios where safety is the main objective. LÄS MER

    Sammanfattning : Convolutional Neural Network (CNN) has been established as a powerful toolto automate various computer vision tasks without requiring any aprioriknowledge. Printed Circuit Board (PCB) manufacturers want to improve theirproduct quality by employing vision based automatic optical inspection (AOI)systems at PCB assembly manufacturing. LÄS MER

  5. 4. Utveckling av ny teknik för hjärtpulsdetektion

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Jabar Zaeid; Andreas Lind; [2017]
    Nyckelord :Signal Processing; Medical Technology; Pulse Detection; ECG Registration; Atrial fibrillation; QRS-complex; Signalbehandling; Medicinteknik; Pulsdetektion; EKG-registrering; Förmaksflimmer; QRS-komplex;

    Sammanfattning : In this thesis we suggest a technique for detecting pulses by signal processing of a raw ECG signal registered from 4 electrodes located on the left upper arm. The signal processing is performed in Matlab and consists of normalization, lowpass filtering, highpass filtering, derivation, squaring and a moving average window to reduce interference. LÄS MER

    Sammanfattning : Atrial fibrillation is a common heart arrhythmia which is characterized by a missing or irregular contraction of the atria. The disease is a risk factor for other more serious diseases and the total medical costs in society are extensive. Therefore it would be beneficial to improve and optimize the prevention and detection of the disease. LÄS MER
