  2. 1. Multifont recognition System for Ethiopic Script

    Author : Yaregal Assabie Lake; Josef Bigun; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ethiopic character recognition; OCR; Multifont recognition; Amharic; Direction fields; Structural and syntactic pattern recognition; Image analysis; Bildanalys;

    Abstract : In this thesis, we present a general framework for multi-font, multi-size and multi-style Ethiopic character recognition system. We propose structural and syntactic techniques for recognition of Ethiopic characters where the graphically comnplex characters are represented by less complex primitive structures and their spatial interrelationships.

  4. 2. Machine-Printed and Handwritten Ethiopic Script Recognition

    Author : Yaregal Assabie; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; HMM; Handwriting Recognition; OCR; Direction Field Tensor; Ethiopic Character Recognition; Amharic Word Recognition; Structure Tensor;

    Abstract : A written language is represented by using machine-printed or handwritten symbols called characters. For automatic recognition of written languages, handwritten script can be captured offline (by a scanner) and online (by electronic digital devices), whereas machine-printed text is captured offline.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Printed Sinhala characters; Electronics; Photonics; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Although substantial research has been carried out on Optical Character Recognition (OCR) where a printed or a handwritten document of script is read as an image and converted to the editable text format, for various languages during the last 30 years, majority of Brahmi descended south Asian scripts are yet to achieve a commercial OCR system....

  6. 4. Ocular counter-rolling during head tilt

    Author : Tony Pansell; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Eye movements; Ocular torsion; VOR; head tilt; Vision.;

    Abstract : When tilting the head towards the shoulder there are numerous mechanisms influencing on the generation and maintenance of ocular counter-roll. Each of these mechanisms has its own temporal and spatial characteristics which influences on the counter-rolled eye position. READ MORE

  7. 5. Laparoscopic and open surgery for colon cancer : studies on costs and health related quality of life

    Author : Martin Janson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Colon cancer is one of the most common forms of cancer in the Western world, and the basis for treatment is surgery. Laparoscopic colon resection (LCR) has been developed since the early 1990s. Short- and longterm outcomes between LCR and open colon resection (OCR) have been compared in randomised controlled trials (RCTs). READ MORE
