  1. 1. Peripheral Vision Adaptive Optics and Psychophysics

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Robert Rosén; KTH.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is about our peripheral vision. Peripheral vision is poor compared to central vision, due to both neural and optical factors. The optical factors include astigmatism, defocus and higher order aberrations consisting mainly of coma. Neurally, the density of ganglion cells decreases towards the periphery, which limits the sampling density. READ MORE

  2. 2. 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

  3. 3. 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.

  4. 4. Spatial vision in diverse invertebrates

    University dissertation from Lund University, Faculty of Science, Department of Biology

    Author : John Kirwan; Lunds universitet.; Lund University.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vision; visual ecology; invertebrates; spatial resolution; behaviour;

    Abstract : Förmågan att uppfatta ljus och vilken riktning det kommer från är utomordentligt användbart för djur. Därför är det inte förvånande att denna förmåga återfinns hos i stort sett varje större djurgrupp, även bland de som anses enkla, såsom koraller och spolmaskar. READ MORE

  5. 5. Computational Methods for Computer Vision : Minimal Solvers and Convex Relaxations

    University dissertation from Lund University, Faculty of Science, Department of Biology

    Author : Viktor Larsson; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Geometric Vision; minimal solvers; Convex relaxation; Pose estimation;

    Abstract : Robust fitting of geometric models is a core problem in computer vision. The most common approach is to use a hypothesize-and-test framework, such as RANSAC. In these frameworks the model is estimated from as few measurements as possible, which minimizes the risk of selecting corrupted measurements. READ MORE
