1. 1. Expressing emotions through vibration for perception and control

   Detta är en avhandling från Umeå : Umeå universitet, Institutionen för tillämpad fysik och elektronik

   Författare :Shafiq ur Réhman; Umeå universitet.; [2010]
   Nyckelord :TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; Multimodal Signal Processing; Mobile Communication; Vibrotactile Rendering; Locally Linear Embedding; Object Detection; Human Facial Expression Analysis; Lip Tracking; Object Tracking; HCI; Expectation-Maximization Algorithm; Lipless Tracking; Image Analysis; Visually Impaired.; datoriserad bildanalys; Computerized Image Analysis; Computing Science; administrativ databehandling; elektronik; Electronics; systemanalys; Systems Analysis;

   Sammanfattning : This thesis addresses a challenging problem: “how to let the visually impaired ‘see’ others emotions”. We, human beings, are heavily dependent on facial expressions to express ourselves. A smile shows that the person you are talking to is pleased, amused, relieved etc. LÄS MER

3. 2. Time-Lapse Microscopy Imaging and Image Analysis for Cell Migration Studies

   Detta är en avhandling från Chalmers University of Technology

   Författare :Johan Degerman; Chalmers tekniska högskola.; Chalmers University of Technology.; [2008]
   Nyckelord :TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; Time-lapse microscopy; cell image segmentation; cell migration modelling; computational imaging;

   Sammanfattning : This thesis considers a complete automatic system for in-vitro cell imaging and migration image analysis. The development of such can be divided into three main problems: The first considered problem concerns how to build a robust time-lapse sequence acquisition system, for imaging adult hippocampal cells in bright-field microscopy.

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

   Detta är en avhandling från Department of Electroscience

   Författare :Hongtu Jiang; Lunds universitet.; Lund University.; [2007]
   Nyckelord :TEKNIKVETENSKAP; TECHNOLOGY; Bildbehandling; Signal processing; image processing; Imaging; Teknik; Technological sciences; Controller Synthesis; Circuit design; FPGA; Image convolution; Image processing; Video segmentation; Signalbehandling; Electronics; Elektronik;

   Sammanfattning : 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.

5. 4. Fuzzy Similarity-based Image Processing

   Detta är en avhandling från Örebro : Örebro universitetsbibliotek

   Författare :Gustav Tolt; Örebro universitet.; Örebro universitet.; [2005]
   Nyckelord :TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; industriell mätteknik; Bildanalys; Bildanalys;

   Sammanfattning : Computer vision problems require low-level operations, e.g. noise reduction and edge detection, as well as high-level operations, e.g. LÄS MER

7. 5. Filter Bank Techniques for Signal and Image Processing

   Detta är en avhandling från Örebro : Örebro universitetsbibliotek

   Författare :Farook Sattar; Lunds universitet.; Lund University.; [1996]
   Nyckelord :TEKNIKVETENSKAP; TECHNOLOGY; Higher-order statistics; Imaging; Detection; Echo cancelling; Multirate system; Multiscale; Image enhancement; Time-frequency analysis and synthesis; Non-stationary signals; Filter bank; Non-parametric estimation; image processing; Bildbehandling; Signal processing; Signalbehandling;

   Sammanfattning : This thesis consists of five parts, each of which considers methods based on filter banks for different applications in signal and image processing. In Part I, a non-parametric estimation method is proposed using filter banks to estimate signals with varying waveforms and arrival times. LÄS MER
