  4. 3. Enhancement, Detection, and Visualization of 3D Volume Data

    Författare :Qingfen Lin; Tony Lindeberg; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Three-dimensional (3D) volume data become increasingly common with the emergence and wide availability of modern 3D image acquisition techniques. The demand for computerized analysis and visualization techniques is constantly growing to utilize the abundant information embedded in these data.This thesis consists of two parts. LÄS MER

  5. 4. A Variational Approach to Image Diffusion in Non-Linear Domains

    Författare :Freddie Åström; Michael Felsberg; Tony Lindeberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Image filtering methods are designed to enhance noisy images captured in situations that are problematic for the camera sensor. Such noisy images originate from unfavourable illumination conditions, camera motion, or the desire to use only a low dose of ionising radiation in medical imaging. LÄS MER
