  1. 1. Design Issues in VLSI Implementation of Image Processing Hardware Accelerators - Methodology and Implementation

    University dissertation from Department of Electroscience, Lund University

    Author : Hongtu Jiang; Lunds universitet.; Lund University.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Bildbehandling; image processing; Imaging; Teknik; Technological sciences; Controller Synthesis; Circuit design; FPGA; Image convolution; Image processing; Video segmentation; Signalbehandling; Electronics; Elektronik;

    Abstract : With the increasing capacity in today's hardware system design enabled by technology scaling, image processing algorithms with substantially more complexity can be implemented in a single chip with real-time performance. Combined with the demand for low power consumption or larger resolution seen in many applications such as mobile devices and HDTV, new design methodologies and hardware architectures are constantly called for to bridge the gap between designers productivity and what the technology could offer.

  3. 3. Learning Convolution Operators for Visual Tracking

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Martin Danelljan; Linköpings universitet.; Linköpings universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Visual tracking is one of the fundamental problems in computer vision. Its numerous applications include robotics, autonomous driving, augmented reality and 3D reconstruction. In essence, visual tracking can be described as the problem of estimating the trajectory of a target in a sequence of images. READ MORE

  5. 5. Quality and motion estimation for image sequence coding

    University dissertation from Linköping : Linköpings universitet

    Author : Kenneth Andersson; Linköpings universitet.; Linköpings universitet.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

    Abstract : Since the advent of television obtaining high perceived quality using a limited bandwidth has been an important issue. This thesis proposes methods inspired and based on the human visual system for exploitation of temporal and perceptual redundancy in image sequences to achieve lower coding rate and/ or higher visual quality.
