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

    Author : Erik Bylow; Mathematical Imaging Group; []
    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

  4. 7. Higher-Order Regularization in Computer Vision

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

    Abstract : 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. READ MORE

  5. 8. Semi-Autonomous Navigation of Powered Wheelchairs : 2D/3D Sensing and Positioning Methods

    Author : Cristian Vilar; Mattias O'Nils; Silvia Krug; Nicolas Ragot; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3D object recognition; YOLO; YOLO-Tiny; 3DHOG; Histogram-of-Oriented-Gradients; ModelNet40; Feature descriptor; Intel RealSense; Depth camera; Wheelchair;

    Abstract : Autonomous driving and assistance systems have become a reality for the automotive industry to improve driving safety in the car. Hence, the cars use a variety of sensors, cameras and image processing techniques to measure their surroundings and control their direction, braking and speed for obstacle avoidance or autonomously driving applications.

  6. 9. Perceptually Motivated Constraints on 3D Visualizations

    Author : Camilla Forsell; Mats Lind; Thomas Porathe; Uppsala universitet; []
    Keywords : Människa-dator-interaktion; Perception; 3D; Human-Computer Interaction; Information visualization; User studies; Människa-dator-interaktion;

    Abstract : This thesis addresses some important characteristics of human visual perception and their implications for three-dimensional (3D) information visualization. The effort can be divided into two parts. First, findings from vision science are explored and validated. READ MORE

  7. 10. Gameplay (3D Game Engine + Ray Tracing = Visual Attention through Eye Tracking)

    Author : Charlotte Sennersten; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Spelutveckling; Game development; Cognition; Vision; Gameplay; Instrumentation; 3D Game Engine; Eyegaze tracking;

    Abstract : Research into gameplay can contribute to more self-conscious approaches to design, allowing designers to create effective gameplay with less testing, or to target specific cognitive and emotional affects of gameplay for serious games applications. Self-conscious design includes theoretically motivated design of game systems to facilitate gameplay motivated by cognitive, scientific and/or rhetorical theories of game affect and functionality.
