  2. 1. Robust Visual Object Tracking mean shift, particle filters and point features

    Author : Zulfiqar Hasan Khan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PF; MSEPF; mean shift; visual object tracking; RANSAC; SIFT; SURF;

    Abstract : Visual object tracking has been identified as a promising technique for many computer vision applications like surveillance, flight navigation, video compression and driver assistance. The main idea is to find the state ofthe object and how it changes over time, in recursive video frames. READ MORE

  4. 2. Interest Curves : Concept, Evaluation, Implementation and Applications

    Author : Bo Li; Ulrik Söderström; Haibo Li; Björn Kruse; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scale-invariance; edge; corner; curve; line; matching; object detection; signalbehandling; Signal Processing;

    Abstract : Image features play important roles in a wide range of computer vision applications, such as image registration, 3D reconstruction, object detection and video understanding. These image features include edges, contours, corners, regions, lines, curves, interest points, etc. READ MORE

  5. 3. Image analysis of prostate cancer tissue biomarkers

    Author : Giuseppe Lippolis; Malmö Urologisk cancerforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; image analysis; Time Resolved Fluorescence; automated Gleason; PSA; AR; fusion gene; TMAs;

    Abstract : Prostate cancer is the second most common cancer in men. In order to improve diagnosis and prognosis, new sensitive and specific biomarkers are needed. Tissue biomarkers carry expression and morphological information of the tissue where they are expressed. READ MORE

  6. 4. Conceptualizations of childhood, pedagogy and educational research in the postmodern : A critical interpretation

    Author : Mariam Meynert; Pedagogik; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Over the last fifty years the debate between modernism and postmodernism has surfaced in the disciplines of social sciences. Epistemologically, there is a shift away from the concept of a “found” world, “out there”, objective, knowable and factual, towards a concept of “constructed” worlds, thus problematizing postulates based on the autonomous, stable, unified, essentialized, coherent and integrated subject capable of rational action, and opening up spaces for a new understanding of subjectivity that is based on provisionality and contingency.

  7. 5. Low Level Operations and Learning in Computer Vision

    Author : Björn Johansson; Gösta Granlund; Rudolf Mester; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis presents some concepts and methods for low level computer vision and learning, with object recognition as the primary application.An efficient method for detection of local rotational symmetries in images is presented. Rotational symmetries include circle patterns, star patterns, and certain high curvature patterns. READ MORE
