  1. 1. Higher-Order Regularization in Computer Vision

    Författare :Johannes Ulén; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Regularization; Segmentation; Dense Stereo;

    Sammanfattning : At the core of many computer vision models lies the minimization of an objective function consisting of a sum of functions with few arguments. The order of the objective function is defined as the highest number of arguments of any summand. LÄS MER

  2. 2. Segmentation of forest patches and estimation of canopy cover using 3D information from stereo photogrammetry

    Författare :Ann-Helen Granholm; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; AGRICULTURAL SCIENCES;

    Sammanfattning : 3D information extracted by image matching of aerial images, so called image-based point clouds, have been found to provide accurate vegetation height measurements. This has led to an increased interest from the vegetation mapping community, since aerial images are an affordable alternative to airborne laser scanner (ALS) data. LÄS MER

  3. 3. Optimization Methods for 3D Reconstruction : Depth Sensors, Distance Functions and Low-Rank Models

    Författare :Erik Bylow; Mathematical Imaging Group; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; 3D Reconstruction;

    Sammanfattning : This thesis explores methods for estimating 3D models using depth sensors andfinding low-rank approximations of matrices. In the first part we focus on how toestimate the movement of a depth camera and creating a 3D model of the scene. LÄS MER

  4. 4. Deep Learning Assisted Visual Odometry

    Författare :Jiexiong Tang; Patric Jensfelt; Davison Andrew; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The capabilities to autonomously explore and interact with the environmenthas always been a greatly demanded capability for robots. Varioussensor based SLAM methods were investigated and served for this purposein the past decades. LÄS MER

  5. 5. Global Pose Estimation from Aerial Images : Registration with Elevation Models

    Författare :Bertil Grelsson; Michael Felsberg; Per-Erik Forssén; Kalle Åström; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Over the last decade, the use of unmanned aerial vehicles (UAVs) has increased drastically. Originally, the use of these aircraft was mainly military, but today many civil applications have emerged. LÄS MER
