  1. 6. Image Reconstruction Techniques using Kaiser Window in 2D CT Imaging

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Md Monowarul Islam; Muftadi Ullah Arpon; [2020]
    Nyckelord :CT Imaging; Parallel-Beam Projection; 2D FFT; Radon Transform; Filters; Window Functions; Kaiser window; Inverse Fourier Transform; FBP.;

    Sammanfattning : The traditional Computed Tomography (CT) is based on the Radon Transform and its inversion. The Radon transform uses parallel beam geometry and its inversion is based on the Fourier slice theorem. LÄS MER

  2. 7. How accuracy of estimated glottal flow waveforms affects spoofed speech detection performance

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

    Författare :Johannes Deivard; [2020]
    Nyckelord :computer science; machine learning; automatic speech verification; spoofed speech detection; glottal flow waveform; glottal inverse filtering; artificial neural network; logistic regression; support vector machine; classifiers;

    Sammanfattning : In the domain of automatic speaker verification,  one of the challenges is to keep the malevolent people out of the system.  One way to do this is to create algorithms that are supposed to detect spoofed speech. LÄS MER

  3. 8. Parking Map Generation and Tracking Using Radar : Adaptive Inverse Sensor Model

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Mohamed Mahmoud; [2020]
    Nyckelord :Vehicle; Parking; Radar; 2D Mapping; SLAM; Occupancy Grid Map; Binary Bayes Filter; Inverse Sensor Model; Noise Analysis;

    Sammanfattning : Radar map generation using binary Bayes filter or what is commonly known as Inverse Sensor Model; which translates the sensor measurements into grid cells occupancy estimation, is a classical problem in different fields. In this work, the focus will be on development of Inverse Sensor Model for parking space using 77 GHz FMCW (Frequency Modulated Continuous Wave) automotive radar, that can handle different environment geometrical complexity in a parking space.

  4. 9. Machine Learning in Defensive IT Security: Early Detection of Novel Threats

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

    Författare :Ren Duan; [2019]
    Nyckelord :;

    Sammanfattning : The rapid development of technology leads to a rise in cybercrime, hence cybersecurityis of unprecedented significance, especially for businesses. Defensiveand forensic IT security is a rather niche field in IT security but it issurely going to grow. It focuses on preventing attacks by good design standardsand the education of persons. LÄS MER

  5. 10. SORTED : Serial manipulator with Object Recognition Trough Edge Detection

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Rikard Bodén; Jonathan Pernow; [2019]
    Nyckelord :Mechatronics; Inverse kinematics; Camera vision; Barrel distortion; Object recognition; Colour filtering; Edge detection; Mekatronik; Invers kinematik; Kamerasensor; Fish-eye förvrängning; Objektigenkänning; Färgigenkänning; Kantdetektering;

    Sammanfattning : Today, there is an increasing demand for smart robots that can make decisions on their own and cooperate with humans in changing environments. The application areas for robotic arms with camera vision are likely to increase in the future of artificial intelligence as algorithms become more adaptable and intelligent than ever. LÄS MER
