  1. 11. Interpolation Techniques with Applications in Video Coding

    Författare :Jens Ogniewski; Per-Erik Forssén; Haibo Li; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Recent years have seen the advent of RGB+D video (color+depth video), which enables new applications like free-viewpoint video, 3D and virtual reality. This is however achieved by adding additional data, thus increasing the bitrate. LÄS MER

  3. 12. Continuous Models for Cameras and Inertial Sensors

    Författare :Hannes Ovrén; Per-Erik Forssen; Klas Nordberg; David Törnqvist; Frank Dellaert; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Using images to reconstruct the world in three dimensions is a classical computer vision task. Some examples of applications where this is useful are autonomous mapping and navigation, urban planning, and special effects in movies. LÄS MER

  4. 13. Visual Odometryin Principle and Practice

    Författare :Mikael Persson; Michael Felsberg; Klas Nordberg; Per-Erik Forssén; Janne Heikkilä; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Visual Odometry; Continuous Pose Trajectory; P3P; PNP; VO; Tracking; Calibration;

    Sammanfattning : Vision is the primary means by which we know where we are, what is nearby, and how we are moving. The corresponding computer-vision task is the simultaneous mapping of the surroundings and the localization of the camera. This goes by many names of which this thesis uses Visual Odometry. LÄS MER

  5. 14. Geometric Computer Vision for Rolling-shutter and Push-broom Sensors

    Författare :Erik Ringaby; Per-Erik Forssén; Anders Heyden; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rolling shutter cmos video rectification stabilisation push-broom kinect;

    Sammanfattning : Almost all cell-phones and camcorders sold today are equipped with a CMOS (Complementary Metal Oxide Semiconductor) image sensor and there is also a general trend to incorporate CMOS sensors in other types of cameras. The sensor has many advantages over the more conventional CCD (Charge-Coupled Device) sensor such as lower power consumption, cheaper manufacturing and the potential for on-chip processing. LÄS MER
