  1. 1. Visual Attention in Active Vision Systems Attending, Classifying and Manipulating Objects

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Babak Rasolzadeh; KTH.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; visual attention; saliency map; compter vision; robotics; active vision; machine learning;

    Abstract : This thesis has presented a computational model for the combination of bottom-up and top-down attentional mechanisms. Furthermore, the use for this model has been demonstrated in a variety of applications of machine and robotic vision. READ MORE

  2. 2. Camera Modelling and Calibration for Machine Vision Applications

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Anders Ryberg; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Camera Calibration; Camera Modelling; Stereo Vision; Machine Vision; Pose Measurement; Computer Vision;

    Abstract : This thesis describes camera based methods for determining positions and orientations of objects in 3D-space. These methods are useful in several applications where camera images are used for acquiring information about the surroundings, and the targeted application here is guiding robots using a camera mounted on the robot hand.

  3. 3. Holistic Grasping: Affordances, Grasp Semantics, Task Constraints

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Martin Hjelm; KTH.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; robotics; robotic grasping; grasping; cognition; embodied cognition; computer vision; machine learning; artificial intelligence; AI; Gaussian process; Gaussian process latent variable model; GPLVM; 3D vision; point cloud features; robotik; manipulation; datorseende; maskininlärning; artificiell intelligens; kognition; Datalogi; Computer Science;

    Abstract : Most of us perform grasping actions over a thousand times per day without giving it much consideration, be it from driving to drinking coffee. Learning robots the same ease when it comes to grasping has been a goal for the robotics research community for decades. READ MORE

  4. 4. Contributions to 3D Image Analysis using Discrete Methods and Fuzzy Techniques With Focus on Images from Cryo-Electron Tomography

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Magnus Gedda; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; digital image analysis; 3D; fuzzy; algorithms; grey-weighted distance; region growing; electron tomography; tracing; fluorescence microscopy; Datoriserad bildanalys; Computerized Image Analysis;

    Abstract : With the emergence of new imaging techniques, researchers are always eager to push the boundaries by examining objects either smaller or further away than what was previously possible. The development of image analysis techniques has greatly helped to introduce objectivity and coherence in measurements and decision making. READ MORE

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

    University dissertation from Department of Mathematics, Lund University

    Author : Erik Bylow; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; 3D Reconstruction;

    Abstract : 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. READ MORE
