  1. 1. Investigation of Registration Methods for High Resolution SAR-EO Imagery

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Niclas Hansson; [2022]
    Nyckelord :SAR; FFT; MI; Image Registration;

    Sammanfattning : With advancements in space technology, remote sensing applications, and computer vision, significant improvements in the data describing our planet are seen today. Researchers want to gather different kinds of data and perform data fusion techniques between them to increase our understanding of the world. LÄS MER

  3. 2. Automatic Alignment Detection and Correction in Infrared and Visual Image Pairs

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Ida Bjerwe; [2020]
    Nyckelord :;

    Sammanfattning : Previously well aligned image sensors, mounted on the same camera, might become misaligned depending on external vibrations. It is of interest to be able to automatically detect and correct for this misalignment, and to separate the deviation into pointing- and/or parallax errors. LÄS MER

  4. 3. Implementation and Evaluation of a Variety of Image Stitching Methods

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Tristan Wright; [2020]
    Nyckelord :;

    Sammanfattning : Image stitching includes image registration and image merging. Image registration can be categorized into area based, frequency based, feature based, and—a recent addition—learning-based methods. As it is not straightforward to assess stitching accuracy, a metric is adopted for measuring stitching error. LÄS MER

  5. 4. Automatic detection of manipulated packages by image comparison

    Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Remi Blateyron; [2016]
    Nyckelord :intensity-based feature-based registration differentiation comparison suspicious manipulated packages;

    Sammanfattning : Shipping companies have a lot of difficulties to control and screen packages such as mail or different types of cargo that may contain dangerous or illegal goods. This project has the goal to enhance the supply chain security by elaborating a way to automatically detect manipulated packages. LÄS MER

  7. 5. Überatlas: Robust speed-up of feature-based registration and multi-atlas based segmentation

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Jennifer Alvén; [2015]
    Nyckelord :computer vision; medical image analysis; feature-based registration; segmentation of pericardium; segmentation of brain; multi-atlas based segmentation; Mathematics and Statistics;

    Sammanfattning : Registration is a key component in multi-atlas approaches to medical image segmentation. Current state-of-the-art uses intensity-based registration methods, but such methods tend to be slow and sensitive to large amount of noise and anatomical abnormalities present in medical images.
