2. 1. Face Recognition : A Single View Based HMM Approach

   Author : Hung Son Le; Haibo Li; Josef Bigun; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; face recognition; pattern recognition; computer vision; HMM; Hidden Markov Models; contrast enhancement; pyramid fusion; image processing; Computer science; Datavetenskap;

   Abstract : This dissertation addresses the challenges of giving computers the ability of doing face recognition, i.e. discriminate between different faces. Face recognition systems are commonly trained with a database of face images, becoming “familiar” with the given faces. READ MORE

4. 2. Automated Tissue Image Analysis Using Pattern Recognition

   Author : Jimmy Azar; Anders Hast; Ewert Bengtsson; Martin Simonsson; Marco Loog; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tissue image analysis; pattern recognition; digital histopathology; immunohistochemistry; paired antibodies; histological stain evaluation; Computerized Image Processing; Datoriserad bildbehandling;

   Abstract : Automated tissue image analysis aims to develop algorithms for a variety of histological applications. This has important implications in the diagnostic grading of cancer such as in breast and prostate tissue, as well as in the quantification of prognostic and predictive biomarkers that may help assess the risk of recurrence and the responsiveness of tumors to endocrine therapy.

5. 3. 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.

7. 5. Pattern Recognition Methods for Oral Lesion Classification using Digital Color Images

   Author : Artur Chodorowski; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oral lesions; supervised classification; pattern recognition; computer-aided diagnosis; support vector machines; color; cancer; shape;

   Abstract : The present thesis addresses the development and application of pattern recognition methods for classification of oral lesions using digital color images as input. The human oral cavity is a site of numerous diseases and two of the common and visually similar lesions are oral leukoplakia and oral lichenoid reactions. READ MORE
