  2. 1. Learning and Optimizing Camera Pose

    Author : Lucas Brynte; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; optimization; structure-from-motion; camera pose estimation; machine learning;

    Abstract : Plenty of computer vision applications involve assessing the position and orientation, i.e. the pose , of one or several cameras, including object pose estimation, visual  localization, and structure-from-motion. READ MORE

  4. 2. Local spatio-temporal image features for motion interpretation

    Author : Ivan Laptev; KTH; []
    Keywords : computer vision; motion; recognition; scale-space;

    Abstract : Visual motion carries information about the dynamics of ascene. Automatic interpretation of this information isimportant when designing computer systems forvisualnavigation, surveillance, human-computer interaction, browsingof video databases and other growing applications.

  5. 3. Solutions and their ambiguities for structure and motion problems

    Author : Magnus Oskarsson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; surveying; navigation; autonomously guided vehicles; motion; Computer vision; structure; Mathematics; Matematik;

    Abstract : This thesis revolves around the problem of solving the structure and motion problem in computer vision. This is the problem of reconstructing the world, the structure, from images taken by a number of cameras undergoing an unknown motion. READ MORE

  6. 4. Towards Reliable and Accurate Global Structure-from-Motion

    Author : José Pedro Lopes Iglesias; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bundle adjustment; point set registration; camera calibration; global SfM; Structure-from-Motion; radial distortion; 3D reconstruction; non-rigid SfM; pOSE; matrix factorization;

    Abstract : Reconstruction of objects or scenes from sparse point detections across multiple views is one of the most tackled problems in computer vision. Given the coordinates of 2D points tracked in multiple images, the problem consists of estimating the corresponding 3D points and cameras' calibrations (intrinsic and pose), and can be solved by minimizing reprojection errors using bundle adjustment.

  7. 5. Automatic Dense Reconstruction from Uncalibrated Video Sequences

    Author : David Nister; KTH; []
    Keywords : Structure from Motion; Calibration; Match Moving; Reconstruction; Video; Computer Vision; Auto-calibration; Augmented Reality; Virtual Reality; Image-based Rendering; Visualisation; Camera Calibration; Motion Estimation;

    Abstract : This thesis describes a system that completely automaticallybuilds a three-dimensional model of a scene given a sequence ofimages of the scene. The system also estimates the internalparameters of the camera and the poses from where the originalimages were taken. READ MORE
