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. Real-Time Algorithms and Intersection Test Methods for Computer Graphics

   Författare :Tomas Möller; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; texture; ray tracing; radiosity; color; three-dimensional graphics and realism; virtual reality; algorithms; shadowing; shading;

   Sammanfattning : In real-time computer graphics applications, at least three major forces are in conflict, namely, rendering speed, the level of realism, and interactivity. Therefore this thesis focuses on real-time algorithms that enhance the realism while maintaining high rendering speed, and on fast intersection test methods in order to speed up, for example, collision detection, picking processes and ray tracing.

5. 4. Representation Learning and Information Fusion : Applications in Biomedical Image Processing

   Författare :Elisabeth Wetzer; Nataša Sladoje; Fred Hamprecht; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Representation Learning; Texture Descriptors; Equivariant Neural Networks; Contrastive Learning; Image Classification; Image Registration; Image Retrieval; Digital Pathology; Computerized Image Processing; Datoriserad bildbehandling;

   Sammanfattning : In recent years Machine Learning and in particular Deep Learning have excelled in object recognition and classification tasks in computer vision. As these methods extract features from the data itself by learning features that are relevant for a particular task, a key aspect of this remarkable success is the amount of data on which these methods train.

7. 5. Appearance characterisation of textured polymeric surfaces

   Författare :Ingrid Arino; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; appearance; reflectance; polymer; colour; surface texture; gloss;

   Sammanfattning : Appearance demands for industrial products are generally increasing since they are closely related to the overall quality impression. Consequently, there is a need to define appearance through its main descriptors, which are gloss, colour and surface texture, as well as the relations between them. LÄS MER
