1. 1. Automatic Virus Identification using TEM : Image Segmentation and Texture Analysis

   Författare :Gustaf Kylberg; Ida-Maria Sintorn; Gunilla Borgefors; Walter Kropatsch; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image analysis; image processing; virus identification; transmission electron microscopy; texture analysis; texture descriptors; Computerized Image Processing; Datoriserad bildbehandling;

   Sammanfattning : Viruses and their morphology have been detected and studied with electron microscopy (EM) since the end of the 1930s. The technique has been vital for the discovery of new viruses and in establishing the virus taxonomy. Today, electron microscopy is an important technique in clinical diagnostics. LÄS MER

3. 2. The Texture-Transform : An Operator for Texture Detection and Discrimination

   Författare :Alireza Tavakoli Targhi; Jan-Olof Eklundh; Arnold Smeulders; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datalogi;

   Sammanfattning : In this thesis we present contributions related to texture detection and discrimination to be used for analyzing real world images. Many computer vision applications can benefit from a fast and low dimensional texture descriptor. LÄS MER

4. 3. Texture based duplex-board layer segmentation

   Författare :Arash Fayyazi; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : A serial scanning electron microscopy images of paper was obtained by a slicing procedure The slicing procedure leads to misregistrations that have to be corrected. Two methods for registration of consecutive images are presented here.Duplex-board is used mainly for packaging liquids. It has a triple layer structure. LÄS MER

5. 4. Spatially Adaptive Analysis and Segmentation of Polarimetric SAR Data

   Författare :Wei Wang; Yifang Ban; Jianwei Wan; Xiaoxiang Zhu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polarimetric SAR; Spatially adaptive; Edge detection; Spherically invariant random vector SIRV ; Superpixel; Simple linear iterative clustering SLIC ; Entropy rate; Segmentation;

   Sammanfattning : In recent years, Polarimetric Synthetic Aperture Radar (PolSAR) has been one of the most important instruments for earth observation, and is increasingly used in various remote sensing applications. Statistical modelling and scattering analysis are two main ways for PolSAR data interpretation, and have been intensively investigated in the past two decades. LÄS MER

7. 5. Visualisation and Generalisation of 3D City Models

   Författare :Bo Mao; Yifang Ban; Lars Harrie; Monika Sester; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D city models; visualisation; generalisation; multiple representation structure; similarity evaluation; aggregation; typification; shell model; street index; texture compression; texture segmentation; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : 3D city models have been widely used in various applications such as urban planning, traffic control, disaster management etc. Efficient visualisation of 3D city models in different levels of detail (LODs) is one of the pivotal technologies to support these applications. LÄS MER
