  1. 21. Foreground detection in specific outdoor scenes : A review of recognized techniques and proposed improvements for a real-time GPU-based implementation in C++

    Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Gustav Sandström; [2016]
    Nyckelord :foreground detection; background subtraction; background removal; real-time image processing;

    Sammanfattning : Correct insertion of computer graphics into live-action broadcasts of outdoor sports requires precise knowledge of the foreground, i.e. players present in the scene. This thesis proposes a foreground detection and segmentation- framework with focus on real-time performance for 1080p resolution. LÄS MER

  3. 22. Accuracy of Quantification for Renography with 99mTc-MAG3: A Study on Virtual and Clinical Data

    Master-uppsats, Lunds universitet/Medicinsk strålningsfysik, Lund

    Författare :Irma Ceric; [2016]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Aim: Renography with 99mTc-MAG3 is one of the most common nuclear medicine examinations. It’s extensive use justifies a thorough investigation of the methods used to accurately determine the split renal function, for instance with regard to background subtraction and correction for renal depth differ- ences.

  4. 23. Detektering, målföljning och identifiering med robotsystem 90

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Simon Lindgren; [2015]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The objective was to clarify whether and how it is possible to detect, track and identify with an EO/IR (electro optical/infrared) sensor. Moreover, the sight of robotic system 90 was tested in order to clarify the possibilities of using it as a sensor. The sight has a field of view of 3x4° with the TV camera and 4x6° with the IRV camera. LÄS MER

  5. 24. Multi-person tracking system for complex outdoor environments

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Cristina-Madalina Tanase; [2015]
    Nyckelord :video tracking; automated video surveillance; image processing.;

    Sammanfattning : The thesis represents the research in the domain of modern video tracking systems and presents the details of the implementation of such a system. Video surveillance is a high point of interest and it relies on robust systems that interconnect several critical modules: data acquisition, data processing, background modeling, foreground detection and multiple object tracking.

  7. 25. Effektiv subtraktionsundervisning i praktiken : Subtraktions- undervisning, strategier och diagnoskonstruktion för en årskurs 2

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för naturvetenskapernas och matematikens didaktik

    Författare :Ida Gustafsson; [2015]
    Nyckelord :matematik; subtraktion; helklassundervisning;

    Sammanfattning : The aim with this study was to investigate the content and form of the subtraction education in a second grade classroom. Three issues were focused. First how the subtraction education was held in a specific second grade classroom, second how a subtraction test could be made and last what subtraction strategies and knowlege the students showed.
